Chemical Structure
Description
The occurrence of 16-Phosphonohexadecanoic acid 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.
16-Phosphonohexadecanoic acid (CAS 443361-18-0), molecular formula C16H33O5P and molecular weight 336.40 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, 16-Phosphonohexadecanoic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 336.40 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
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), 16-Phosphonohexadecanoic 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.
