Chemical Structure
Description
The occurrence of Mometasone Furoate EP Impurity T is closely related to a steroid core, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Mometasone Furoate EP Impurity T (CAS CATO-C4X-170420), a pharmacopoeial impurity reference standard (molecular formula C27H29Cl3O6, MW 555.87 g/mol) used for the identification and quantification of trace impurities in APIs.
The molecular framework of Mometasone Furoate EP Impurity T (C27H29Cl3O6) is characterized by a steroid core, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), Mometasone Furoate EP Impurity T 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.
