Chemical Structure
Description
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.
3-bromo-4-chloro-1-[(4-methoxyphenyl)methyl]pyrazolo[3,4-b]pyridine (CAS 1854056-69-1), molecular formula C14H25BrClN3O and molecular weight 366.72 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-bromo-4-chloro-1-[(4-methoxyphenyl)methyl]pyrazolo[3,4-b]pyridine (C14H25BrClN3O) is characterized by an amide group, a hydroxyl group, an ether linkage, chlorine/bromine 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 3-bromo-4-chloro-1-[(4-methoxyphenyl)methyl]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.
