Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (5E)-5-{[(4-methoxyphenyl)amino]methylidene}-2H,3H,4H,5H-indeno[1,2-b]thiopyran-4-one.

(5E)-5-{[(4-methoxyphenyl)amino]methylidene}-2H,3H,4H,5H-indeno[1,2-b]thiopyran-4-one (CAS 338757-87-2) is a high-purity analytical reference standard with the molecular formula C20H17NO2S and a molecular weight of 335.42 g/mol.

Structurally, (5E)-5-{[(4-methoxyphenyl)amino]methylidene}-2H,3H,4H,5H-indeno[1,2-b]thiopyran-4-one (C20H17NO2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 335.42 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
