Chemical Structure
Description
Structurally, Empagliflozin Impurity 312 (C18H18ClIO2) contains a steroid core, a hydroxyl group, an ether linkage, chlorine/iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 428.69 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Empagliflozin Impurity 312 (CAS CATO-C4X-1065312) is a certified pharmaceutical impurity reference standard with the molecular formula C18H18ClIO2 and a molecular weight of 428.69 g/mol.
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.
As a certified reference material (CRM), Empagliflozin Impurity 312 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
