4-[(2-hydroxyethyl)amino]-3-nitrobenzoic acid CAS 59320-14-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-[(2-hydroxyethyl)amino]-3-nitrobenzoic acid.

CATO supplies 4-[(2-hydroxyethyl)amino]-3-nitrobenzoic acid (CAS 59320-14-8), a certified reference material (molecular formula C9H10N2O5, MW 226.19 g/mol) for analytical method development and quality control.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 4-[(2-hydroxyethyl)amino]-3-nitrobenzoic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 226.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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-[(2-hydroxyethyl)amino]-3-nitrobenzoic acid 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.
