Description
CATO manufactures 6-Bromo-3-(tert-butyl)-2H-indazole 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.
6-Bromo-3-(tert-butyl)-2H-indazole (CAS 1781663-14-6) is a high-purity analytical reference standard with the molecular formula C11H13BrN2 and a molecular weight of 253.14 g/mol.
The molecular framework of 6-Bromo-3-(tert-butyl)-2H-indazole (C11H13BrN2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, 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.
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.
