Description
CATO manufactures (2-Chloro-5-nitrophenyl)(3,4-dimethylphenyl)methanone under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
CATO supplies (2-Chloro-5-nitrophenyl)(3,4-dimethylphenyl)methanone (CAS 70132-77-3), a certified reference material (molecular formula C15H12ClNO3, MW 289.71 g/mol) for analytical method development and quality control.
Based on its molecular formula C15H12ClNO3, (2-Chloro-5-nitrophenyl)(3,4-dimethylphenyl)methanone contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 289.71 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
