Chemical Structure

Methyl 3-cyano-1H-indazole-5-carboxylate CAS 1190319-99-3 chemical structure

Description

The occurrence of Methyl 3-cyano-1H-indazole-5-carboxylate is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Methyl 3-cyano-1H-indazole-5-carboxylate (CAS 1190319-99-3), molecular formula C10H7N3O2 and molecular weight 201.18 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Methyl 3-cyano-1H-indazole-5-carboxylate (C10H7N3O2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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).

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.

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.
