Chemical Structure

(Z)-11-Octadecenal CAS 4273-95-4 chemical structure

Description

The occurrence of (Z)-11-Octadecenal is closely related to a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(Z)-11-Octadecenal (CAS 4273-95-4), molecular formula C18H34O and molecular weight 266.46 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a hydroxyl group, an ether linkage, (Z)-11-Octadecenal is typically white to off-white low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 266.46 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), (Z)-11-Octadecenal 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.
