Chemical Structure

Octadecanedioic Acid CAS 871-70-5 chemical structure

Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

Octadecanedioic Acid (CAS 871-70-5) is a high-purity analytical reference standard with the molecular formula C18H34O4 and a molecular weight of 314.46 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Octadecanedioic Acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 314.46 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.

As a certified reference material (CRM), Octadecanedioic 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.
