Chemical Structure
Description
Tauroursodeoxycholic Acid Dihydrate (CAS 117609-50-4), molecular formula C26H45NO6S and molecular weight 499.70 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Tauroursodeoxycholic Acid Dihydrate (C26H45NO6S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 499.70 g/mol, it falls into the moderately-high-molecular-weight range. 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), Tauroursodeoxycholic Acid Dihydrate 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.
