Chemical Structure

7-Amino-4-methyl-1H-indazole CAS 952183-44-7 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.

CATO supplies 7-Amino-4-methyl-1H-indazole (CAS 952183-44-7), a certified reference material (molecular formula C8H9N3, MW 147.18 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 7-Amino-4-methyl-1H-indazole is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 147.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

As a certified reference material (CRM), 7-Amino-4-methyl-1H-indazole meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
