Chemical Structure

Sodium p-n-undecylbenzenesulfonate CAS 20466-34-6 chemical structure

Description

Owing to a steroid core, a sulfone group, a hydroxyl group, an ether linkage, Sodium p-n-undecylbenzenesulfonate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 335.46 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Sodium p-n-undecylbenzenesulfonate (CAS 20466-34-6) is a high-purity analytical reference standard with the molecular formula C17H28O3SNa and a molecular weight of 335.46 g/mol.

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 p-n-undecylbenzenesulfonate 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.
