4-Chloro-N,N-diisopropyl-3-nitrobenzamide CAS 352443-08-4

Description

Compared with other compounds in its class, the molecular weight of 284.74 g/mol gives 4-Chloro-N,N-diisopropyl-3-nitrobenzamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-Chloro-N,N-diisopropyl-3-nitrobenzamide (CAS 352443-08-4), molecular formula C13H17ClN2O3 and molecular weight 284.74 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-Chloro-N,N-diisopropyl-3-nitrobenzamide (C13H17ClN2O3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
