Chemical Structure

(1S)-(+)-10-Camphorsulfonic acid CAS 98673-87-1 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

(1S)-(+)-10-Camphorsulfonic acid (CAS 98673-87-1), molecular formula C10H16O4SH2O and molecular weight 250.31 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, (1S)-(+)-10-Camphorsulfonic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 250.31 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.
