Chemical Structure

11-Phenoxyundecanoic acid CAS 7170-44-7 chemical structure

Description

The occurrence of 11-Phenoxyundecanoic acid is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

11-Phenoxyundecanoic acid (CAS 7170-44-7) is a high-purity analytical reference standard with the molecular formula C17H26O3 and a molecular weight of 278.39 g/mol.

Structurally, 11-Phenoxyundecanoic acid (C17H26O3) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 278.39 g/mol, it falls into the medium-molecular-weight range. 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), 11-Phenoxyundecanoic acid 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.
