Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 228.28 g/mol gives Docusate Impurity (Z)-Mono-2-Ethylhexyl Maleate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Docusate Impurity (Z)-Mono-2-Ethylhexyl Maleate (CAS 7423-42-9) is a certified pharmaceutical impurity reference standard with the molecular formula C12H20O4 and a molecular weight of 228.28 g/mol.
The molecular framework of Docusate Impurity (Z)-Mono-2-Ethylhexyl Maleate (C12H20O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
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 Docusate Impurity (Z)-Mono-2-Ethylhexyl Maleate 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.
