5-Cyano-3-methyl-N-((((4-methylbenzyl)oxy)imino)methyl)-4-phenylthiophene-2-carboxamide (CAS 343372-49-6) is a high-purity analytical reference standard with the molecular formula C22H19N3O2S and a molecular weight of 389.47 g/mol.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 5-Cyano-3-methyl-N-((((4-methylbenzyl)oxy)imino)methyl)-4-phenylthiophene-2-carboxamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 389.47 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
