Chemical Structure

Bis(2-ethylhexyl) maleate CAS 142-16-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 340.50 g/mol gives Bis(2-ethylhexyl) maleate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Bis(2-ethylhexyl) maleate (CAS 142-16-5), molecular formula C20H36O4 and molecular weight 340.50 g/mol, is a CATO reference standard with documented purity and traceability.

Bis(2-ethylhexyl) maleate (C20H36O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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 Bis(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.
