Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 365.56 g/mol gives Calcium 4-dodecylbenzenesulfonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Calcium 4-dodecylbenzenesulfonate (CAS 47236-10-2) is a high-purity analytical reference standard with the molecular formula C18H29O3SCa and a molecular weight of 365.56 g/mol.
Owing to a steroid core, a sulfone group, a hydroxyl group, an ether linkage, Calcium 4-dodecylbenzenesulfonate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 365.56 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), Calcium 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.
