Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 409.56 g/mol gives Cholic Acid-24-13C distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Cholic Acid-24-13C (CAS 52886-36-9), molecular formula C23[13C]H40O5 and molecular weight 409.56 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Cholic Acid-24-13C (C23[13C]H40O5) contains a steroid core, 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 409.56 g/mol, it falls into the moderately-high-molecular-weight range. 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.
