Chemical Structure
Description
Sodium 4-dodecylbenzenesulfonate (CAS 2211-98-5) is a high-purity analytical reference standard with the molecular formula C18H29O3SNa and a molecular weight of 348.48 g/mol.
Owing to a steroid core, a sulfone group, a hydroxyl group, an ether linkage, Sodium 4-dodecylbenzenesulfonate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 348.48 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Sodium 4-dodecylbenzenesulfonate 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.
