Description
CATO manufactures Fluocinolone Acetonide Impurity 41 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
Fluocinolone Acetonide Impurity 41 (CAS CATO-C4X-238141) is a certified pharmaceutical impurity reference standard with the molecular formula C23H26F2O7 and a molecular weight of 452.45 g/mol.
Based on its molecular formula C23H26F2O7, Fluocinolone Acetonide Impurity 41 contains a flavonoid core, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 452.45 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
