Chemical Structure

Sodium octadecyl sulfate CAS 1120-04-3 chemical structure

Description

Sodium octadecyl sulfate (CAS 1120-04-3), molecular formula C18H37O4SNa and molecular weight 372.54 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Sodium octadecyl sulfate (C18H37O4SNa) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 0.5, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 372.54 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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

CATO manufactures Sodium octadecyl sulfate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
