1-(2-(2-(3-Hydroxybenzylidene)hydrazinyl)-4-methylthiazol-5-yl)ethan-1-one CAS 464211-86-7

Description

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.

1-(2-(2-(3-Hydroxybenzylidene)hydrazinyl)-4-methylthiazol-5-yl)ethan-1-one (CAS 464211-86-7) is a high-purity analytical reference standard with the molecular formula C13H13N3O2S and a molecular weight of 275.33 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 1-(2-(2-(3-Hydroxybenzylidene)hydrazinyl)-4-methylthiazol-5-yl)ethan-1-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 275.33 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.

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.
