5-Ethynyl-2-(methylthio)pyrimidine CAS 87573-81-7 chemical structure

Description

CATO manufactures 5-Ethynyl-2-(methylthio)pyrimidine 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.

CATO supplies 5-Ethynyl-2-(methylthio)pyrimidine (CAS 87573-81-7), a certified reference material (molecular formula C7H6N2S, MW 150.20 g/mol) for analytical method development and quality control.

The molecular framework of 5-Ethynyl-2-(methylthio)pyrimidine (C7H6N2S) is characterized by a nitrile group, sulfur-containing functionality, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
