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-Nitrophenyl Phenyl Ether.
CATO supplies 4-Nitrophenyl Phenyl Ether (CAS 620-88-2), a certified reference material (molecular formula C12H9NO3, MW 215.20 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-Nitrophenyl Phenyl Ether is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 215.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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-Nitrophenyl Phenyl Ether 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.
