Chemical Structure
Description
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.
CATO supplies 5-Amino-6-chloro-1H-pyrimidin-4-one (CAS 3137-60-8), a certified reference material (molecular formula C4H4ClN3O, MW 145.55 g/mol) for analytical method development and quality control.
Owing to an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 5-Amino-6-chloro-1H-pyrimidin-4-one is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 145.55 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.
