6-Chloro-1,4-dimethyl-3-(thiophen-2-yl)-1H-pyrazolo[3,4-b]pyridine (CAS 650592-18-0), molecular formula C12H10ClN3S and molecular weight 263.75 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6-Chloro-1,4-dimethyl-3-(thiophen-2-yl)-1H-pyrazolo[3,4-b]pyridine (C12H10ClN3S) 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 6-Chloro-1,4-dimethyl-3-(thiophen-2-yl)-1H-pyrazolo[3,4-b]pyridine 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.
