Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 233.18 g/mol gives Isosorbide Dinitrate Impurity 8 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Isosorbide Dinitrate Impurity 8 (CAS 39698-15-2), a pharmacopoeial impurity reference standard (molecular formula C8H11NO7, MW 233.18 g/mol) used for the identification and quantification of trace impurities in APIs.
Structurally, Isosorbide Dinitrate Impurity 8 (C8H11NO7) contains a carbohydrate-derived structure, an amide group. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 233.18 g/mol, it falls into the medium-molecular-weight range. 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.
CATO manufactures Isosorbide Dinitrate Impurity 8 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
