Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 312.28 g/mol gives Bosentan Impurity N8 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Bosentan Impurity N8 (CAS 329923-15-1) is a certified pharmaceutical impurity reference standard with the molecular formula C15H12N4O4 and a molecular weight of 312.28 g/mol.
Structurally, Bosentan Impurity N8 (C15H12N4O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 312.28 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 manufactures Bosentan Impurity N8 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.
