Chemical Structure

6-Iodo-4-methyl-1H-indazole-3-carboxylic acid CAS 885521-24-4 chemical structure

Description

CATO manufactures 6-Iodo-4-methyl-1H-indazole-3-carboxylic 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.

6-Iodo-4-methyl-1H-indazole-3-carboxylic acid (CAS 885521-24-4) is a high-purity analytical reference standard with the molecular formula C9H7IN2O2 and a molecular weight of 302.07 g/mol.

6-Iodo-4-methyl-1H-indazole-3-carboxylic acid (C9H7IN2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, iodine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
