Propofol EP Impurity A CAS 2934-05-6 chemical structure

Description

As a certified reference material (CRM), Propofol EP Impurity A 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.

Propofol EP Impurity A (CAS 2934-05-6) is a certified pharmaceutical impurity reference standard with the molecular formula C12H18O and a molecular weight of 178.27 g/mol.

Based on its molecular formula C12H18O, Propofol EP Impurity A contains a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 178.27 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
