2-Ethylhexanoic anhydride CAS 36765-89-6 chemical structure

Description

CATO manufactures 2-Ethylhexanoic anhydride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

2-Ethylhexanoic anhydride (CAS 36765-89-6), molecular formula C16H30O3 and molecular weight 270.41 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C16H30O3, 2-Ethylhexanoic anhydride contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 270.41 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
