Bisacodyl EP Impurity E CAS 111664-35-8 chemical structure

Description

Bisacodyl EP Impurity E (CAS 111664-35-8) is a certified pharmaceutical impurity reference standard with the molecular formula C22H19NO4 and a molecular weight of 361.39 g/mol.

Based on its molecular formula C22H19NO4, Bisacodyl EP Impurity E contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 361.39 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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 Bisacodyl EP Impurity E 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.
