Chemical Structure

5,6-Dimethyl-2-(methylthio)-4-pyrimidinamine CAS 14394-63-9 chemical structure

Description

5,6-Dimethyl-2-(methylthio)-4-pyrimidinamine (CAS 14394-63-9), molecular formula C7H11N3S and molecular weight 169.25 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C7H11N3S, 5,6-Dimethyl-2-(methylthio)-4-pyrimidinamine contains a nitrile group, sulfur-containing functionality, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 169.25 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

CATO manufactures 5,6-Dimethyl-2-(methylthio)-4-pyrimidinamine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
