Chemical Structure
Description
The occurrence of 5-fluoro-2-nitrophenyl 2-chlorobenzoate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 5-fluoro-2-nitrophenyl 2-chlorobenzoate (CAS 219689-81-3), a certified reference material (molecular formula C13H7ClFNO4, MW 295.65 g/mol) for analytical method development and quality control.
Based on its molecular formula C13H7ClFNO4, 5-fluoro-2-nitrophenyl 2-chlorobenzoate contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 295.65 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 5-fluoro-2-nitrophenyl 2-chlorobenzoate 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.
