Chemical Structure

1-Methyl-1H-indazole-5-carbonitrile CAS 189107-45-7 chemical structure

Description

As a certified reference material (CRM), 1-Methyl-1H-indazole-5-carbonitrile 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.

CATO supplies 1-Methyl-1H-indazole-5-carbonitrile (CAS 189107-45-7), a certified reference material (molecular formula C9H7N3, MW 157.17 g/mol) for analytical method development and quality control.

The molecular framework of 1-Methyl-1H-indazole-5-carbonitrile (C9H7N3) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
