Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Methyl 5-(2,4-dichlorophenyl)oxazole-4-carboxylate (CAS 89204-94-4) is a high-purity analytical reference standard with the molecular formula C11H7Cl2NO3 and a molecular weight of 272.08 g/mol.
The molecular framework of Methyl 5-(2,4-dichlorophenyl)oxazole-4-carboxylate (C11H7Cl2NO3) is characterized by a nitrogen-containing heterocyclic scaffold, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures Methyl 5-(2,4-dichlorophenyl)oxazole-4-carboxylate 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.
