Chemical Structure

Cacodylic Acid Sodium Salt Trihydrate CAS 124-65-2 chemical structure

Description

The occurrence of Cacodylic Acid Sodium Salt Trihydrate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Cacodylic Acid Sodium Salt Trihydrate (CAS 124-65-2), molecular formula C2H6AsO2Na and molecular weight 159.98 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Cacodylic Acid Sodium Salt Trihydrate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 159.98 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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), Cacodylic Acid Sodium Salt Trihydrate 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.
