Chemical Structure
Description
The molecular framework of (3-Amino-4-(4-methoxyphenyl)-6-phenylthieno[2,3-b]pyridin-2-yl)(3,4-dihydroquinolin-1(2H)-yl)methanone (C30H25N3O2S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
(3-Amino-4-(4-methoxyphenyl)-6-phenylthieno[2,3-b]pyridin-2-yl)(3,4-dihydroquinolin-1(2H)-yl)methanone (CAS 332101-74-3), molecular formula C30H25N3O2S and molecular weight 491.60 g/mol, is a CATO reference standard with documented purity and traceability.
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.
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.
