Chemical Structure

琼斯试剂 CAS 65272-70-0 chemical structure

Description

琼斯试剂 (CAS 65272-70-0), molecular formula CrO3H2O4S and molecular weight 198.07 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a sulfone group, 琼斯试剂 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 198.07 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.
