Chemical Structure
Description
The occurrence of (5-Chloro-1,3,4-thiadiazol-2-yl)methanol is closely related to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (5-Chloro-1,3,4-thiadiazol-2-yl)methanol (CAS 912669-58-0), a certified reference material (molecular formula C3H3ClN2OS, MW 150.59 g/mol) for analytical method development and quality control.
(5-Chloro-1,3,4-thiadiazol-2-yl)methanol (C3H3ClN2OS) contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
