Chemical Structure
Description
Barium yttrium tungsten oxide (CAS 37265-86-4), molecular formula O9WY2Ba and molecular weight 642.97 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an inorganic composition, Barium yttrium tungsten oxide is typically white to off-white amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 642.97 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
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.
