Sigma-Aldrich Product Search API

The Sigma-Aldrich Product Search API provides programmatic access to the Sigma-Aldrich product catalog containing hundreds of thousands of chemical compounds, reagents, biochemicals, and laboratory supplies. Researchers and laboratory information management systems (LIMS) can query products by CAS number, catalog number, product name, or chemical structure (SMILES notation) to retrieve product details, safety data, pricing, and availability information.
