Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 319.15 g/mol gives 4-Bromo-2-formylphenyl 4-methylbenzoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-Bromo-2-formylphenyl 4-methylbenzoate (CAS 431937-89-2), molecular formula C15H11BrO3 and molecular weight 319.15 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Bromo-2-formylphenyl 4-methylbenzoate (C15H11BrO3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, bromine 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.
CATO manufactures 4-Bromo-2-formylphenyl 4-methylbenzoate 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.
