The connector, listed in the Microsoft Marketplace with Microsoft as publisher and no listed price, is a federated connector built on the Model Context Protocol that fetches content live under each user's own credentials, and each user needs a Microsoft 365 Copilot license with access governed by the organization's CAS subscriptions. CAS interim president Tim Wahlberg said scientists in drug discovery and chemical R&D \"rely on CAS as an authoritative source for what is known about a substance, a reaction, or a target.", "body_md": "CAS, the scientific information division of the American Chemical Society, has made its data available inside Microsoft 365 Copilot. The [connector, announced Oct. 20](https://www.prnewswire.com/news-releases/cas-collaborates-with-microsoft-to-enable-faster-innovation-in-pharmaceutical-life-sciences-and-chemical-industries-302911752.html), gives Copilot customers access to the CAS Content Collection and CAS Newton, the company’s agentic AI assistant, from apps including Word, Teams and PowerPoint, CAS says. It extends CAS Connections, an integration framework CAS launched in June that also supports the [Model Context Protocol (MCP)](https://www.anthropic.com/news/model-context-protocol), the open standard Anthropic introduced in November 2024.\n\nCAS pitches the connector at work that happens outside the lab, in documents, chats and slide decks. In the release, CAS describes a chemist drafting the experimental section of a report in Word who can confirm a compound’s CAS Registry Number and structure, check reaction conditions and reagent availability against CAS records, and cite the source while writing. An intellectual property analyst in Teams can check whether a substance appears in the patent literature, and a business development analyst building a licensing briefing in PowerPoint can add patent-landscape information that traces back to CAS content. The connector is listed in the [Microsoft Marketplace](https://marketplace.microsoft.com/en-us/product/WA200012172), with Microsoft as publisher and no listed price. [CAS’s product page](https://www.cas.org/solutions/cas-connections) says access through CAS Connections “is governed by your organization’s CAS subscriptions,” and each user needs a Microsoft 365 Copilot license.\n\nMicrosoft classes CAS Connections as a [federated connector](https://learn.microsoft.com/en-us/microsoft-365/copilot/connectors/federated-connectors-overview), one that uses MCP to fetch content live under each user’s own credentials. Microsoft says federated connectors “don’t copy or store data in Microsoft 365,” and that administrators can limit a connector to specific users or groups and audit activity in Microsoft Purview.\n\nCAS and Microsoft frame the integration around access to reliable scientific information. “Scientists in drug discovery and chemical R&D rely on CAS as an authoritative source for what is known about a substance, a reaction, or a target,” Tim Wahlberg, CAS’s interim president, said in the release. Chantrelle Nielsen, principal product manager for the Copilot platform at Microsoft, said pharmaceutical, life sciences and chemical customers “need AI they can trust, grounded in reliable scientific information.”\n\nThe Copilot connector is part of a series of CAS AI announcements this year. In April, CAS [launched CAS Newton](https://www.cas.org/press-releases/meet-cas-newton-agentic-ai-built-for-science) inside its SciFinder and BioFinder platforms and as a standalone interface. In June, it [introduced CAS Connections](https://www.cas.org/press-releases/cas-connections), a framework for embedding CAS data and Newton in other R&D tools. First-phase partners were Albert Invent, Sapio Sciences, Inductive Bio, Scilligence and Wolfram Research, and the June release said the framework supported “AI platform integrations for tools such as Anthropic’s Claude and Microsoft Copilot.” In September, CAS [announced a collaboration with Novartis Biomedical Research](https://www.cas.org/press-releases/cas-announces-collaboration-with-novartis-to-advance-ai-ready-reaction-informatics) to search Novartis’s internal reaction data alongside the CAS Content Collection, which CAS says holds more than 160 million scientist-curated reactions.\n\nCAS’s integrations are part of a broader expansion of scientific content into general-purpose AI assistants. Microsoft’s federated connector list for health and life sciences places CAS alongside BioRender, ClinicalTrials.gov, Consensus, Clarivate’s Cortellis Regulatory Intelligence and Open Targets, and its reference category includes ChEMBL, DrugBank, PubMed and bioRxiv. Anthropic’s Claude [connects to](https://www.anthropic.com/news/healthcare-life-sciences) life sciences sources including Benchling, PubMed, ChEMBL, Open Targets and Wiley Scholar Gateway. The two AI ecosystems also overlap: Microsoft [added Anthropic’s Claude models](https://claude.com/resources/articles/claude-now-available-in-microsoft-365-copilot) alongside OpenAI’s in September 2025, starting with the Researcher agent and Copilot Studio.\n\nChemistry databases are also expanding access through other integration routes. Elsevier says data from Reaxys, its chemistry database and a rival to CAS SciFinder, can be [integrated into discovery and predictive-modeling workflows](https://www.elsevier.com/products/reaxys) through MCP, APIs or flat files under a separate license. Within Reaxys itself, Elsevier added [natural-language AI search](https://www.elsevier.com/about/press-releases/elsevier-introduces-reaxys-ai-search-enabling-faster-and-more-accessible) to Reaxys in July 2025.\n\nFor Microsoft, bringing chemistry data into Office is one part of a broader push into scientific R&D. Alongside these Copilot integrations, the company has developed [Microsoft Discovery](https://azure.microsoft.com/en-us/blog/announcing-microsoft-discovery-general-availability-and-microsoft-discovery-app-preview/), a separate platform for agentic AI workflows in science and engineering. [PhysicsX](https://www.physicsx.ai/newsroom/physicsx-forges-strategic-collaboration-with-microsoft-to-accelerate-engineering-innovation-with-ai-for-science-platform), an engineering-simulation developer, was a launch partner when Microsoft introduced Discovery in May 2025. Microsoft made the platform generally available in June 2026, naming early users including [Syensqo](https://rcpmag.com/articles/2026/06/02/microsoft-discovery-reaches-ga.aspx), which is applying agentic AI to heat transfer fluids for semiconductor manufacturing.", "url": "https://wpnews.pro/news/150-years-of-cas-chemistry-data-comes-to-microsoft-copilot", "canonical_source": "https://www.rdworldonline.com/150-years-of-cas-chemistry-data-comes-to-microsoft-copilot/", "published_at": "2026-10-21 19:31:27+00:00", "updated_at": "2026-10-28 09:42:14.549613+00:00", "lang": "en", "topics": ["ai-agents", "agent-protocols", "ai-products", "artificial-intelligence"], "entities": ["CAS", "American Chemical Society", "Microsoft", "Microsoft 365 Copilot", "CAS Newton", "CAS Connections", "Model Context Protocol", "Anthropic"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/150-years-of-cas-chemistry-data-comes-to-microsoft-copilot", "markdown": "https://wpnews.pro/news/150-years-of-cas-chemistry-data-comes-to-microsoft-copilot.md", "text": "https://wpnews.pro/news/150-years-of-cas-chemistry-data-comes-to-microsoft-copilot.txt", "jsonld": "https://wpnews.pro/news/150-years-of-cas-chemistry-data-comes-to-microsoft-copilot.jsonld"}}
