Chemical Structure
Description
Cholic Acid Impurity 67 (CAS CATO-C4X-116067) is a certified pharmaceutical impurity reference standard with the molecular formula C26H44O4C25H38O5C26H40O4C24H36O5 and a molecular weight of 1660.36 g/mol.
Based on its molecular formula C26H44O4C25H38O5C26H40O4C24H36O5, Cholic Acid Impurity 67 contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 1660.36 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
