Chemical Structure

5-Amino-6-methyl-1H-indazole CAS 81115-45-9 chemical structure

Description

As a certified reference material (CRM), 5-Amino-6-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.

5-Amino-6-methyl-1H-indazole (CAS 81115-45-9), molecular formula C8H9N3 and molecular weight 147.18 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5-Amino-6-methyl-1H-indazole (C8H9N3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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.

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.
