Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies Phosphoric acid, monooctadecyl ester, zinc salt (1:1) (CAS 4615-31-0), a certified reference material (molecular formula C18H37O4PZn, MW 413.84 g/mol) for analytical method development and quality control.
The molecular framework of Phosphoric acid, monooctadecyl ester, zinc salt (1:1) (C18H37O4PZn) is characterized by a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), Phosphoric acid, monooctadecyl ester, zinc salt (1:1) 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.
