Chemical Structure
Description
Benzenesulfonic acid, 4-ethenyl-, calcium salt, polymer with 1,4-diethenylbenzene (CAS 69943-73-3), molecular formula C8H7O3SC10H10Ca and molecular weight 353.47 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Benzenesulfonic acid, 4-ethenyl-, calcium salt, polymer with 1,4-diethenylbenzene (C8H7O3SC10H10Ca) is characterized by a steroid core, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), Benzenesulfonic acid, 4-ethenyl-, calcium salt, polymer with 1,4-diethenylbenzene 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.
