2-(3-Chloro-4-nitrophenyl)acetic acid CAS 163395-25-3 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 2-(3-Chloro-4-nitrophenyl)acetic acid.

2-(3-Chloro-4-nitrophenyl)acetic acid (CAS 163395-25-3) is a high-purity analytical reference standard with the molecular formula C8H6ClNO4 and a molecular weight of 215.59 g/mol.

2-(3-Chloro-4-nitrophenyl)acetic acid (C8H6ClNO4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), 2-(3-Chloro-4-nitrophenyl)acetic acid 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.
