3-Formyl-1h-indazole-4-carbonitrile CAS 797804-56-9 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 3-Formyl-1h-indazole-4-carbonitrile (CAS 797804-56-9), a certified reference material (molecular formula C9H5N3O, MW 171.16 g/mol) for analytical method development and quality control.

3-Formyl-1h-indazole-4-carbonitrile (C9H5N3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
