Chemical Structure
Description
As a certified reference material (CRM), Daclatasvir Impurity 27 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.
Daclatasvir Impurity 27 (CAS 1009119-83-8) is a certified pharmaceutical impurity reference standard with the molecular formula C26H28N6HCl and a molecular weight of 461.01 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, Daclatasvir Impurity 27 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 461.01 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.
