Nonylphosphonic acid CAS 4730-79-4 chemical structure

Description

As a certified reference material (CRM), Nonylphosphonic 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.

Nonylphosphonic acid (CAS 4730-79-4), molecular formula C9H21O3P and molecular weight 208.24 g/mol, is a CATO reference standard with documented purity and traceability.

Nonylphosphonic acid (C9H21O3P) contains a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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.
