Chemical Structure
Description
5-(Methylthio)benzo[c][1,2,5]oxadiazole (CAS 53439-76-2), molecular formula C7H6N2OS and molecular weight 166.20 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-(Methylthio)benzo[c][1,2,5]oxadiazole (C7H6N2OS) is characterized by an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 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.
CATO manufactures 5-(Methylthio)benzo[c][1,2,5]oxadiazole 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.
