Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 192.08 g/mol gives Sevoflurane Impurity 7 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Sevoflurane Impurity 7 (CAS 158076-92-7), a pharmacopoeial impurity reference standard (molecular formula C5H5F5O2, MW 192.08 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, Sevoflurane Impurity 7 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 192.08 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), Sevoflurane Impurity 7 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.
