Chemical Structure

Ethyl 2-cyclododecylideneacetate CAS 1903-26-0 chemical structure

Description

Ethyl 2-cyclododecylideneacetate (CAS 1903-26-0) is a high-purity analytical reference standard with the molecular formula C16H28O2 and a molecular weight of 252.39 g/mol.

Ethyl 2-cyclododecylideneacetate (C16H28O2) 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 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), Ethyl 2-cyclododecylideneacetate 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.
