Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 290.70 g/mol gives N-Benzyl-2-chloro-4-nitrobenzamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
N-Benzyl-2-chloro-4-nitrobenzamide (CAS 346723-24-8), molecular formula C14H11ClN2O3 and molecular weight 290.70 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, N-Benzyl-2-chloro-4-nitrobenzamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 290.70 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.
As a certified reference material (CRM), N-Benzyl-2-chloro-4-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.
