Chemical Structure

4-chloro-1-methyl-7-nitro-indazol-3-amine CAS 1192263-90-3 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-chloro-1-methyl-7-nitro-indazol-3-amine.

CATO supplies 4-chloro-1-methyl-7-nitro-indazol-3-amine (CAS 1192263-90-3), a certified reference material (molecular formula C8H15ClN4O2, MW 234.68 g/mol) for analytical method development and quality control.

The molecular framework of 4-chloro-1-methyl-7-nitro-indazol-3-amine (C8H15ClN4O2) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. 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. 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.

As a certified reference material (CRM), 4-chloro-1-methyl-7-nitro-indazol-3-amine 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.
