Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 372.44 g/mol gives Hydroxy Pioglitazone M-IV distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Hydroxy Pioglitazone M-IV (CAS 146062-44-4), a certified reference material (molecular formula C19H20N2O4S, MW 372.44 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Hydroxy Pioglitazone M-IV is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 372.44 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.
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.
