High-quality data makes the critical difference
The CAS Content Collection™ is trusted by innovation leaders world-wide. We integrate our scientist-curated data into your workflows through a collaborative process that tailors content and technologies to best meet your unique objectives.
The CAS application programming interface (API) supports many use cases, like those shown below. Contact us to discuss the best way to speed up your workflows.
Unite data across sources
A single compound is represented in many ways, making it difficult to harmonize data across departments, systems, suppliers, and locations. CAS Registry Numbers (CAS RN), the global universal identifier, can standardize chemical names and structures, add synonyms, and unite data in your LIMS, ELNs, and other internal systems. Read the case study on how Improved Data Integrity Enhances R&D Efficiency.
Focus drug discovery
Access to diverse, high-quality data enables your models to identify and prioritize novel drug candidates more accurately. The CAS Content Collection includes SAR data, as well as biological data such as targets, ligands, and pharmacological properties. Better starting places enable your research efforts to be more focused, improving success and speed-to-market.
Optimize cheminformatics workflows
Directly query the CAS Content Collection in Python or workflow/ETL solutions. Integrate key data such as chemical substances, structures, properties, and reference data to drive the success of virtual screening, machine learning, and predictive analytics.
