Chemical Structure

1-Methyl-1H-indazol-3(2H)-one CAS 1006-19-5 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 1-Methyl-1H-indazol-3(2H)-one (CAS 1006-19-5), a certified reference material (molecular formula C8H8N2O, MW 148.16 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 1-Methyl-1H-indazol-3(2H)-one is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 148.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), 1-Methyl-1H-indazol-3(2H)-one 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.
