Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 440.41 g/mol gives Toremifene Impurity 12 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Toremifene Impurity 12 (CAS CATO-C4X-139712) is a certified pharmaceutical impurity reference standard with the molecular formula C26H26ClNOHCl and a molecular weight of 440.41 g/mol.
Structurally, Toremifene Impurity 12 (C26H26ClNOHCl) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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 440.41 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).
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), Toremifene Impurity 12 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.
