Chemical Structure

Aminophylline EP Impurity D CAS 116131-08-9 chemical structure

Description

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

CATO supplies Aminophylline EP Impurity D (CAS 116131-08-9), a pharmacopoeial impurity reference standard (molecular formula C6H10N4OHCl, MW 190.63 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C6H10N4OHCl, Aminophylline EP Impurity D contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 190.63 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

As a certified reference material (CRM), Aminophylline 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.
