Infobox references

11-Aminoundecanoic acid is an organic compound with the formula H₂N(CH₂)₁₀CO₂H. This white solid is classified as an amine and a fatty acid. 11-Aminoundecanoic acid is a precursor to Nylon-11.^[1]

Preparation

As practiced by Arkema, 11-aminoundecanoic acid is prepared industrially from undecylenic acid, which is derived from castor oil.^[2] Undecylenic acid undergoes anti-Markovnikov hydrobromination in the presence of benzoylperoxide (BPO):

Conversion of the bromide to the amine completes the synthesis:
