Triheptadecanoin  (Synonyms: Glycerol triheptadecanoate; Trimargarin)

Triheptadecanoin (Glycerol triheptadecanoate) is an internal standard for the rapid GC analysis of fatty acid methyl esters in edible fats and oils. Triheptadecanoin enables the quantitative analysis of trans-fatty acid content in edible fats and oils via a rapid GC method. Triheptadecanoin smoothly undergoes methylation with m-TFPTAH in toluene solution at room temperature^[1].

Triheptadecanoin serves as a reliable internal standard for the rapid gas chromatography (GC) analysis of trans fatty acid content in edible oils (including rapeseed oil, olive oil, salad oil, sesame oil, shortening, vegetable fat spreads and margarine). It enables accurate quantification with high repeatability, and the analytical results are comparable to official analytical methods^[1].
Triheptadecanoin undergoes a rapid and stable methylation reaction with m-TFPTAH at room temperature, with a reaction rate exceeding 97%^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
