Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-((3-Cyano-4-(3,4-dimethoxyphenyl)-6-(p-tolyl)pyridin-2-yl)thio)-N-(2,4-dibromophenyl)acetamide.
2-((3-Cyano-4-(3,4-dimethoxyphenyl)-6-(p-tolyl)pyridin-2-yl)thio)-N-(2,4-dibromophenyl)acetamide (CAS 334503-73-0), molecular formula C29H23Br2N3O3S and molecular weight 653.38 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution, 2-((3-Cyano-4-(3,4-dimethoxyphenyl)-6-(p-tolyl)pyridin-2-yl)thio)-N-(2,4-dibromophenyl)acetamide is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 653.38 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
