Chemical Structure
Description
The occurrence of Sodium 4-methoxy-3-(trifluoromethoxy)benzoate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Sodium 4-methoxy-3-(trifluoromethoxy)benzoate (CAS 1804454-48-5), molecular formula C9H6F3O4Na and molecular weight 258.13 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C9H6F3O4Na, Sodium 4-methoxy-3-(trifluoromethoxy)benzoate contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 258.13 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 Sodium 4-methoxy-3-(trifluoromethoxy)benzoate 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.
