Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 593.02 g/mol gives Dapagliflozin Impurity 145 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Dapagliflozin Impurity 145 (CAS 1971128-00-3) is a certified pharmaceutical impurity reference standard with the molecular formula C29H33ClO11 and a molecular weight of 593.02 g/mol.
Structurally, Dapagliflozin Impurity 145 (C29H33ClO11) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 593.02 g/mol, it falls into the moderately-high-molecular-weight range. 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.
CATO manufactures Dapagliflozin Impurity 145 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.
