Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(2,6-Dichlorophenyl)-5-[(E)-2-[(4-methoxyphenyl)amino]ethenyl]-1,2-oxazole-4-carbonitrile.
CATO supplies 3-(2,6-Dichlorophenyl)-5-[(E)-2-[(4-methoxyphenyl)amino]ethenyl]-1,2-oxazole-4-carbonitrile (CAS 338402-68-9), a certified reference material (molecular formula C19H13Cl2N3O2, MW 386.23 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 3-(2,6-Dichlorophenyl)-5-[(E)-2-[(4-methoxyphenyl)amino]ethenyl]-1,2-oxazole-4-carbonitrile is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 386.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
