Chemical Structure

Potassium hexadecyl phosphate CAS 19045-75-1 chemical structure

Description

The occurrence of Potassium hexadecyl phosphate is closely related to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Potassium hexadecyl phosphate (CAS 19045-75-1), molecular formula C16H33O4PK and molecular weight 359.51 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, Potassium hexadecyl phosphate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 359.51 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.

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.

As a certified reference material (CRM), Potassium hexadecyl phosphate 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.
