Chemical Structure

Sodium cetyl/stearyl sulfate CAS 68955-20-4 chemical structure

Description

Sodium cetyl/stearyl sulfate (CAS 68955-20-4) is a high-purity analytical reference standard with the molecular formula C18H37O4SC16H33O4SNa and a molecular weight of 694.04 g/mol.

Sodium cetyl/stearyl sulfate (C18H37O4SC16H33O4SNa) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. 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.
