Chemical Structure
Description
CATO supplies Bis(2,4,6-Trichlorophenyl)Oxalate (CAS 1165-91-9), a certified reference material (molecular formula C14H4Cl6O4, MW 448.90 g/mol) for analytical method development and quality control.
The molecular framework of Bis(2,4,6-Trichlorophenyl)Oxalate (C14H4Cl6O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
