R&D teams work across many platforms. CAS makes their outputs smarter, faster, and more reliable.
Every extra step between a researcher and reliable scientific information is a gap where discovery stalls. Fragmented access to scientific knowledge introduces risk into AI-generated answers and forces researchers to choose between the tools they know and the information they need.
Accelerate discovery
Authoritative chemical and biological knowledge surfaces earlier in the process - right when your researchers need it.
Strengthen AI outputs
AI answers grounded in curated, verifiable scientific sources so every recommendation can be cited and defended.
Support compliance and IP
Auditable, traceable access to CAS content within your secure environment — consistent with the rigorous standards pharma and chemical R&D requires.
Reduce redundant work
Reduce repeated searches and manual data transfer across systems — researchers stay focused on science.
What CAS Connections delivers
Multiple integration paths. One trusted source.
CAS Connections embeds CAS content and CAS Newton agentic AI into your existing tools, agents, and workflows to meet your organization wherever its infrastructure lives. Every integration draws on the full depth of our trusted, curated scientific knowledge.
Data Access
CAS content in your platforms and pipelines
Query CAS content programmatically. Responses feed directly into ELNs, LIMS, discovery platforms, dashboards, and custom applications — structured, reliable data delivered at the point of decision.
AI Integration
Trusted scientific knowledge inside existing AI tools
CAS Newton connects as a knowledge source inside existing AI platforms, so the intelligence powering those tools is grounded in curated, citable content.
Agentic Workflows
CAS Newton in your agent ecosystem
CAS Newton operates within your organization's own multi-agent workflows — passing context and outputs across your tools, pipelines, and automated systems. As your agentic architecture evolves, you can trust that findings and conclusions are backed by scientific knowledge and insights.
