Chemical Structure

3-(4-methylpiperazin-1-yl)-2-nitroaniline CAS 74628-20-9 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 3-(4-methylpiperazin-1-yl)-2-nitroaniline.

CATO supplies 3-(4-methylpiperazin-1-yl)-2-nitroaniline (CAS 74628-20-9), a certified reference material (molecular formula C11H16N4O2, MW 236.27 g/mol) for analytical method development and quality control.

The molecular framework of 3-(4-methylpiperazin-1-yl)-2-nitroaniline (C11H16N4O2) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO manufactures 3-(4-methylpiperazin-1-yl)-2-nitroaniline 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.
