Chemical Structure

4,5-dimethylthiazole-2-carbaldehyde CAS 74531-15-0 chemical structure

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.

CATO supplies 4,5-dimethylthiazole-2-carbaldehyde (CAS 74531-15-0), a certified reference material (molecular formula C6H11NOS, MW 145.22 g/mol) for analytical method development and quality control.

Based on its molecular formula C6H11NOS, 4,5-dimethylthiazole-2-carbaldehyde contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 145.22 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
