Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 537.69 g/mol gives Tauro-β-muricholic Acid Sodium distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Tauro-β-muricholic Acid Sodium (CAS 145022-92-0), molecular formula C26H44NO7SNa and molecular weight 537.69 g/mol, is a CATO reference standard with documented purity and traceability.
Tauro-β-muricholic Acid Sodium (C26H44NO7SNa) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
