Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 2,3-difluoro-4-isopropoxybenzoate.
CATO supplies Ethyl 2,3-difluoro-4-isopropoxybenzoate (CAS 2504203-90-9), a certified reference material (molecular formula C12H14F2O3, MW 244.23 g/mol) for analytical method development and quality control.
The molecular framework of Ethyl 2,3-difluoro-4-isopropoxybenzoate (C12H14F2O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 Ethyl 2,3-difluoro-4-isopropoxybenzoate 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.
