Chemical Structure
Description
As a certified reference material (CRM), 3-[(4-Chloro-3-nitrophenyl)amino]-1-(4-methylphenyl)propan-1-one 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.
3-[(4-Chloro-3-nitrophenyl)amino]-1-(4-methylphenyl)propan-1-one (CAS 882748-63-2), molecular formula C16H15ClN2O3 and molecular weight 318.75 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, 3-[(4-Chloro-3-nitrophenyl)amino]-1-(4-methylphenyl)propan-1-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 318.75 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
