Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-(Benzylthio)-4-chlorobenzo[4,5]thieno[3,2-d]pyrimidine (CAS 478029-84-4), molecular formula C17H11ClN2S2 and molecular weight 342.87 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(Benzylthio)-4-chlorobenzo[4,5]thieno[3,2-d]pyrimidine (C17H11ClN2S2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
CATO manufactures 2-(Benzylthio)-4-chlorobenzo[4,5]thieno[3,2-d]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.
