Chemical Structure
Description
The occurrence of (all-Z)-5,8,11,14-Eicosatetraenylphosphonofluoridic Acid Methyl Ester is closely related to organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(all-Z)-5,8,11,14-Eicosatetraenylphosphonofluoridic Acid Methyl Ester (CAS 188404-10-6), molecular formula C21H36FO2P and molecular weight 370.48 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, (all-Z)-5,8,11,14-Eicosatetraenylphosphonofluoridic Acid Methyl Ester is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 370.48 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), (all-Z)-5,8,11,14-Eicosatetraenylphosphonofluoridic Acid Methyl Ester 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.
