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 4-[(4-Methoxyphenyl)sulfanyl]-2-phenyl-5-pyrimidinecarboxylic acid.
CATO supplies 4-[(4-Methoxyphenyl)sulfanyl]-2-phenyl-5-pyrimidinecarboxylic acid (CAS 477854-63-0), a certified reference material (molecular formula C18H14N2O3S, MW 338.38 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 4-[(4-Methoxyphenyl)sulfanyl]-2-phenyl-5-pyrimidinecarboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 338.38 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.
