4-Amino-1-methyl-1H-indazole CAS 77894-69-0 chemical structure

Description

CATO supplies 4-Amino-1-methyl-1H-indazole (CAS 77894-69-0), a certified reference material (molecular formula C8H9N3, MW 147.18 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 4-Amino-1-methyl-1H-indazole is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 147.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

CATO manufactures 4-Amino-1-methyl-1H-indazole under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
