Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Droperidol EP Impurity D.
As a process- or degradation-related impurity, Droperidol EP Impurity D (CAS 466118-75-2, C22H22FN3O3) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, Droperidol EP Impurity D is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 395.43 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.
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.
CATO manufactures Droperidol EP Impurity D under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
