Chemical Structure
Description
CATO supplies 5-Chloro-4-[(4-chlorophenyl)sulfanyl]-6-methylpyrimidin-2-amine (CAS 343375-75-7), a certified reference material (molecular formula C11H9Cl2N3S, MW 286.18 g/mol) for analytical method development and quality control.
Structurally, 5-Chloro-4-[(4-chlorophenyl)sulfanyl]-6-methylpyrimidin-2-amine (C11H9Cl2N3S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 286.18 g/mol, it falls into the medium-molecular-weight range. 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.
