Chemical Structure
Description
Triethyl Arsenate (CAS 15606-95-8) is a high-purity analytical reference standard with the molecular formula C6H15AsO4 and a molecular weight of 226.10 g/mol.
Triethyl Arsenate (C6H15AsO4) contains 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
