Chemical Structure
Description
Owing to an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 4-Chloro-2-methanesulfinyl-6-methoxy-pyrimidine is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 135.59 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.
CATO supplies 4-Chloro-2-methanesulfinyl-6-methoxy-pyrimidine (CAS 1353979-52-8), a certified reference material (molecular formula C5H9NOHCl, MW 135.59 g/mol) for analytical method development and quality control.
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.
