Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 293.13 g/mol gives Atorvastatin Impurity 102 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Atorvastatin Impurity 102 (CAS 88675-31-4) is a certified pharmaceutical impurity reference standard with the molecular formula C14H10BrFO and a molecular weight of 293.13 g/mol.
Atorvastatin Impurity 102 (C14H10BrFO) contains a hydroxyl group, an ether linkage, fluorine/bromine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
