Chemical Structure
Description
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.
CATO supplies (3-Amino-4-(4-methoxyphenyl)-6-phenylthieno[2,3-b]pyridin-2-yl)(phenyl)methanone (CAS 126888-13-9), a certified reference material (molecular formula C27H20N2O2S, MW 436.52 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, (3-Amino-4-(4-methoxyphenyl)-6-phenylthieno[2,3-b]pyridin-2-yl)(phenyl)methanone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 436.52 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.
