Description
CATO supplies Ethyl 5-fluoro-2-methylbenzoylformate (CAS 732251-76-2), a certified reference material (molecular formula C11H11FO3, MW 210.20 g/mol) for analytical method development and quality control.
The molecular framework of Ethyl 5-fluoro-2-methylbenzoylformate (C11H11FO3) 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. 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.
As a certified reference material (CRM), Ethyl 5-fluoro-2-methylbenzoylformate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
