2-(Benzylthio)-6-chloropyrimidin-4-amine CAS 99983-92-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(Benzylthio)-6-chloropyrimidin-4-amine.

2-(Benzylthio)-6-chloropyrimidin-4-amine (CAS 99983-92-3), molecular formula C11H10ClN3S and molecular weight 251.74 g/mol, is a CATO reference standard with documented purity and traceability.

2-(Benzylthio)-6-chloropyrimidin-4-amine (C11H10ClN3S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

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.
