Chemical Structure

Isoflurane EP Impurity E CAS 32778-09-9 chemical structure

Description

Based on its molecular formula C3Cl3F5O, Isoflurane EP Impurity E contains a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 253.38 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Isoflurane EP Impurity E (CAS 32778-09-9) is a certified pharmaceutical impurity reference standard with the molecular formula C3Cl3F5O and a molecular weight of 253.38 g/mol.

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), Isoflurane EP Impurity E 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.
