Obeticholic Acid Impurity 45 CAS CATO-C4X-115345

Description

Compared with other compounds in its class, the molecular weight of 763.10 g/mol gives Obeticholic Acid Impurity 45 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Obeticholic Acid Impurity 45 (CAS CATO-C4X-115345) is a certified pharmaceutical impurity reference standard with the molecular formula C48H74O7 and a molecular weight of 763.10 g/mol.

Structurally, Obeticholic Acid Impurity 45 (C48H74O7) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 763.10 g/mol, it falls into the high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

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.
