Chemical Structure

Sevoflurane Impurity 12 CAS 206756-25-4 chemical structure

Description

CATO supplies Sevoflurane Impurity 12 (CAS 206756-25-4), a pharmacopoeial impurity reference standard (molecular formula C4H2ClF5O, MW 196.50 g/mol) used for the identification and quantification of trace impurities in APIs.

Sevoflurane Impurity 12 (C4H2ClF5O) contains a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

As a certified reference material (CRM), Sevoflurane 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.
