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 地芬尼多杂质4盐酸盐.
As a process- or degradation-related impurity, 地芬尼多杂质4盐酸盐 (CAS 94908-95-9, C11H21NHCl) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
地芬尼多杂质4盐酸盐 (C11H21NHCl) contains chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), 地芬尼多杂质4盐酸盐 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.
