Chemical Structure

2-Chloro-N-(2-hydroxyphenyl)-5-nitrobenzamide CAS 16398-07-5 chemical structure

Description

As a certified reference material (CRM), 2-Chloro-N-(2-hydroxyphenyl)-5-nitrobenzamide 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.

2-Chloro-N-(2-hydroxyphenyl)-5-nitrobenzamide (CAS 16398-07-5) is a high-purity analytical reference standard with the molecular formula C13H9ClN2O4 and a molecular weight of 292.67 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 2-Chloro-N-(2-hydroxyphenyl)-5-nitrobenzamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 292.67 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.
