Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 206.62 g/mol gives Diethyl Chloromaleate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Diethyl Chloromaleate (CAS 626-10-8), molecular formula C8H11ClO4 and molecular weight 206.62 g/mol, is a CATO reference standard with documented purity and traceability.
Diethyl Chloromaleate (C8H11ClO4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Diethyl Chloromaleate 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.
