Chemical Structure
Description
2-Ethoxy-4-formylphenyl 2-((3-cyano-4-(4-methoxyphenyl)-6-phenylpyridin-2-yl)thio)acetate (CAS 334497-98-2), molecular formula C30H24N2O5S and molecular weight 524.59 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Ethoxy-4-formylphenyl 2-((3-cyano-4-(4-methoxyphenyl)-6-phenylpyridin-2-yl)thio)acetate (C30H24N2O5S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-Ethoxy-4-formylphenyl 2-((3-cyano-4-(4-methoxyphenyl)-6-phenylpyridin-2-yl)thio)acetate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
