Chemical Structure

N,O-Di(2-hydroxyethyl)-2-amino-5-nitrophenol CAS 59820-43-8 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 N,O-Di(2-hydroxyethyl)-2-amino-5-nitrophenol.

N,O-Di(2-hydroxyethyl)-2-amino-5-nitrophenol (CAS 59820-43-8), molecular formula C10H14N2O5 and molecular weight 242.23 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of N,O-Di(2-hydroxyethyl)-2-amino-5-nitrophenol (C10H14N2O5) 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 N,O-Di(2-hydroxyethyl)-2-amino-5-nitrophenol 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.
