Chemical Structure
Description
As a certified reference material (CRM), Sodium cetostearyl sulfate CRS meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
CATO supplies Sodium cetostearyl sulfate CRS (CAS 59186-41-3), a certified reference material (molecular formula C18H37O4SC16H33O4SNa, MW 694.04 g/mol) for analytical method development and quality control.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, Sodium cetostearyl sulfate CRS is typically white to off-white amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 694.04 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.
