Chemical Structure

Glyceryl Trinitrate Solution EP Impurity D CAS 621-65-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 182.09 g/mol gives Glyceryl Trinitrate Solution EP Impurity D distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

As a process- or degradation-related impurity, Glyceryl Trinitrate Solution EP Impurity D (CAS 621-65-8, C3H6N2O7) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Glyceryl Trinitrate Solution EP Impurity D (C3H6N2O7) contains an amino-acid-derived structure, an amide group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; 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), Glyceryl Trinitrate Solution EP Impurity D 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.
