6-Chloro-2-(methylthio)-5-nitropyrimidin-4-amine CAS 38136-96-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 220.64 g/mol gives 6-Chloro-2-(methylthio)-5-nitropyrimidin-4-amine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

6-Chloro-2-(methylthio)-5-nitropyrimidin-4-amine (CAS 38136-96-8), molecular formula C5H5ClN4O2S and molecular weight 220.64 g/mol, is a CATO reference standard with documented purity and traceability.

6-Chloro-2-(methylthio)-5-nitropyrimidin-4-amine (C5H5ClN4O2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 6-Chloro-2-(methylthio)-5-nitropyrimidin-4-amine 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.
