Chemical Structure
Description
The occurrence of 6-Chloropyrimidine-2(1H)-thione is closely related to a nitrile group, sulfur-containing functionality, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 6-Chloropyrimidine-2(1H)-thione (CAS 63096-74-2), a certified reference material (molecular formula C4H3ClN2S, MW 146.60 g/mol) for analytical method development and quality control.
Owing to a nitrile group, sulfur-containing functionality, chlorine substitution, 6-Chloropyrimidine-2(1H)-thione is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 146.60 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
