Abstract

Abstract: Preparation, homogeneity, stability and certification of reference material of octyl gallate were studied. Highly purified reference material of octyl gallate was prepared from an industrial grade product of octyl gallate by solvent re-crystallization in ethanol and water. The content of octyl gallate in reference material was measured by peak area normalization of high performance liquid chromatographic analysis method. The reference materials passed the tests of homogeneity and stability (6 months). The measured mass fraction of octyl gallate reference material was 99.472 0% with uncertainty of 0.03% by certification.

Key words: octyl gallate, reference material, certification, homogeneity, stability
