Description

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.

2-((3,4-Dichlorobenzyl)thio)-N-methyl-6-((phenylthio)methyl)pyrimidin-4-amine (CAS 341965-56-8), molecular formula C19H17Cl2N3S2 and molecular weight 422.39 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-((3,4-Dichlorobenzyl)thio)-N-methyl-6-((phenylthio)methyl)pyrimidin-4-amine (C19H17Cl2N3S2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 422.39 g/mol, it falls into the moderately-high-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.

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.
