(2,5-Dichlorothiazol-4-yl)methanol CAS 1823921-75-0

Description

Compared with other compounds in its class, the molecular weight of 184.04 g/mol gives (2,5-Dichlorothiazol-4-yl)methanol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(2,5-Dichlorothiazol-4-yl)methanol (CAS 1823921-75-0), molecular formula C4H3Cl2NOS and molecular weight 184.04 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, (2,5-Dichlorothiazol-4-yl)methanol is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 184.04 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.
