Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 354.52 g/mol gives Bis(2-ethylhexyl) Itaconate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Bis(2-ethylhexyl) Itaconate (CAS 2287-83-4), molecular formula C21H38O4 and molecular weight 354.52 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Bis(2-ethylhexyl) Itaconate (C21H38O4) 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Bis(2-ethylhexyl) Itaconate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
