Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Spiramycin EP Impurity G Ditrifluoroacetate.
CATO supplies Spiramycin EP Impurity G Ditrifluoroacetate (CAS CATO-C4X-232513), a pharmacopoeial impurity reference standard (molecular formula C38H64N2O12C2HF3O2, MW 854.95 g/mol) used for the identification and quantification of trace impurities in APIs.
Structurally, Spiramycin EP Impurity G Ditrifluoroacetate (C38H64N2O12C2HF3O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 854.95 g/mol, it falls into the 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.
As a certified reference material (CRM), Spiramycin EP Impurity G Ditrifluoroacetate 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.
