Chemical Structure
Description
(3β)-Cholest-5-ene-3,24-diol 24-Methylbenzenesulfonate 3-O-Tetrahydropyranyl Ether (CAS 70141-04-7) is a high-purity analytical reference standard with the molecular formula C36H54O5S and a molecular weight of 598.88 g/mol.
(3β)-Cholest-5-ene-3,24-diol 24-Methylbenzenesulfonate 3-O-Tetrahydropyranyl Ether (C36H54O5S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), (3β)-Cholest-5-ene-3,24-diol 24-Methylbenzenesulfonate 3-O-Tetrahydropyranyl Ether 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.
