Chemical Structure
Description
As a certified reference material (CRM), Sevoflurane Impurity 13 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.
CATO supplies Sevoflurane Impurity 13 (CAS 194039-83-3), a pharmacopoeial impurity reference standard (molecular formula C8H6F12O3, MW 378.11 g/mol) used for the identification and quantification of trace impurities in APIs.
The molecular framework of Sevoflurane Impurity 13 (C8H6F12O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
