The
pentyl valerate and ethyl valerate esters of 3-methyl valeric acid are used as a food additive in the synthetic flavoring substances and adjuvant owing to its fruity flavors.
The O-alkyl (2-18) derivatives were obtained in high yields on refluxing a solution of 1 in 4% methanolicNaOH with alkyl halides (ethyl bromide, butyl bromide, isobutyl bromide,
pentyl bromide, hexyl bromide, heptyl chloride, octyl bromide, nonyl chloride, decyl chloride, allyl bromide, benzyl chloride, 2-iodobenzyl bromide, 3-iodobenzyl bromide, 4-iodobenzyl bromide, 2-nitrobenzyl bromide, 3-nitrobenzyl bromide and 4-nitrobenzyl bromide) and work up.

Also based in the School of Chemistry is Dr Michael Webb, whose research focuses on a compound, called
pentyl pantothenamide, first assessed in the 1970s.
Similarly, the Nacional cacao produced the highest levels of benzoic acid
pentyl ester at day 2 but the levels were negligible after day 3 (Figure 5).
In one example, the anchoring component is trimethoxysilyl, where the linking component may be a
pentyl group and the functional group may be an epoxy group.
All show a significant improvement over using no tail solvent at all, but aromatic 100 (Figure 5, dark blue line) did not enable as high of gloss above 4.5 mils DFT as compared with
pentyl propionate or DIBK.
It is an ester with chemical name Ethanaminium N, N-diethyl N-methyl 2(3 methyl-1-oxo-2 phenyl
pentyl) 13 bromide.
The biosynthetic pathways of the major cannabinoids with
pentyl side chains (CBC, CBC, CBG, and THC) were established in the 1990s.
