Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Dysprosium(III) acetate hydrate.
Dysprosium(III) acetate hydrate (CAS 304675-49-8) is a high-purity analytical reference standard with the molecular formula C3H9DyCO2H2O and a molecular weight of 269.63 g/mol.
Dysprosium(III) acetate hydrate (C3H9DyCO2H2O) 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.
