Chemical Structure
Description
The occurrence of 2-(5-Fluoro-2-methoxybenzoyl)benzoic acid is closely related to a flavonoid core, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-(5-Fluoro-2-methoxybenzoyl)benzoic acid (CAS 135030-71-6) is a high-purity analytical reference standard with the molecular formula C15H11FO4 and a molecular weight of 274.24 g/mol.
Owing to a flavonoid core, a hydroxyl group, an ether linkage, fluorine substitution, 2-(5-Fluoro-2-methoxybenzoyl)benzoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 274.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 2-(5-Fluoro-2-methoxybenzoyl)benzoic acid 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.
