Dimethylarsinothioic Acid CAS 754217-65-7 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

Dimethylarsinothioic Acid (CAS 754217-65-7), molecular formula C2H7AsOS and molecular weight 154.06 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C2H7AsOS, Dimethylarsinothioic Acid contains sulfur-containing functionality, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 154.06 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
