Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Nalmefene Impurity 14.
As a process- or degradation-related impurity, Nalmefene Impurity 14 (CAS 19493-09-5, C19H17P) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Owing to organophosphorus functionality, a polycyclic aromatic system, Nalmefene Impurity 14 is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 276.31 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), Nalmefene Impurity 14 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.
