Compared with other compounds in its class, the molecular weight of 173.66 g/mol gives 2-Chloro-4,5,6,7-tetrahydro-1,3-benzothiazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2-Chloro-4,5,6,7-tetrahydro-1,3-benzothiazole (CAS 26846-98-0), a certified reference material (molecular formula C7H8ClNS, MW 173.66 g/mol) for analytical method development and quality control.
Owing to a nitrile group, sulfur-containing functionality, chlorine substitution, an aromatic ring system, 2-Chloro-4,5,6,7-tetrahydro-1,3-benzothiazole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 173.66 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.
