Dibutyl sebacate CAS 109-43-3 chemical structure

Description

As a certified reference material (CRM), Dibutyl sebacate 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.

Dibutyl sebacate (CAS 109-43-3) is a high-purity analytical reference standard with the molecular formula C18H34O4 and a molecular weight of 314.46 g/mol.

Dibutyl sebacate (C18H34O4) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
