2-(5-Bromo-1H-indazol-3-yl)acetic acid CAS 885271-84-1

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.

2-(5-Bromo-1H-indazol-3-yl)acetic acid (CAS 885271-84-1), molecular formula C9H7BrN2O2 and molecular weight 255.07 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-(5-Bromo-1H-indazol-3-yl)acetic acid (C9H7BrN2O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. 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.

CATO manufactures 2-(5-Bromo-1H-indazol-3-yl)acetic acid 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.
