Chemical Structure
Description
4-Fluoro-2-nitrophenyl 4-methylbenzoate (CAS 811461-05-9) is a high-purity analytical reference standard with the molecular formula C14H10FNO4 and a molecular weight of 275.23 g/mol.
The molecular framework of 4-Fluoro-2-nitrophenyl 4-methylbenzoate (C14H10FNO4) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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-Fluoro-2-nitrophenyl 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.
