Chemical Structure
Description
Lead hydrogen phosphate,98.00% (CAS 15845-52-0), molecular formula HO4PPb and molecular weight 303.18 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a phosphate ester group, Lead hydrogen phosphate,98.00% is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 303.18 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.
