Chemical Structure
Description
The molecular framework of (Chloro(4-nitrophenyl)methylene)dibenzene (C19H14ClNO2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
(Chloro(4-nitrophenyl)methylene)dibenzene (CAS 41273-47-6) is a high-purity analytical reference standard with the molecular formula C19H14ClNO2 and a molecular weight of 323.77 g/mol.
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.
CATO manufactures (Chloro(4-nitrophenyl)methylene)dibenzene 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.
