5-(3,4-Dimethoxyphenyl)-2-(piperidin-1-yl)-[1,3]thiazolo[4,5-b]pyridine-7-carboxylic acid CAS 852388-76-2

Description

5-(3,4-Dimethoxyphenyl)-2-(piperidin-1-yl)-[1,3]thiazolo[4,5-b]pyridine-7-carboxylic acid (CAS 852388-76-2), molecular formula C20H21N3O4S and molecular weight 399.46 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 5-(3,4-Dimethoxyphenyl)-2-(piperidin-1-yl)-[1,3]thiazolo[4,5-b]pyridine-7-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 399.46 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.

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.
