Chemical Structure
Description
2-(4-Fluorophenyl)-5,5-dimethyl-1,3-dioxane-2-butanoic acid (CAS 953805-21-5) is a high-purity analytical reference standard with the molecular formula C16H21FO4 and a molecular weight of 296.33 g/mol.
2-(4-Fluorophenyl)-5,5-dimethyl-1,3-dioxane-2-butanoic acid (C16H21FO4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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-(4-Fluorophenyl)-5,5-dimethyl-1,3-dioxane-2-butanoic 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.
