Isopentyl 3-methylbutanoate (cas: 659-70-1) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.

Quality, sensory and volatile profiles of fresh-cut big top nectarines cold stored in air or modified atmosphere packaging was written by Cozzolino, Rosaria;Cefola, Maria;Pace, Bernardo;Malorni, Livia;Martignetti, Antonella;Montemurro, Nicola;Pellicano, Mario Paolo. And the article was included in International Journal of Food Science and Technology in 2018.COA of Formula: C10H20O2 This article mentions the following:

Solid-phase microextraction (SPME) GC-MS was used to investigate the volatile organic compound (VOC) profile of fresh-cut ‘Big Top’ nectarine samples, stored in unsealed bags (AIR) or packed in active modified atm. (MAP) after 8 days of cold storage. Nectarine slices were also subjected to sensory and quality anal. after harvest and at the end of the storage. MAP preserved the overall quality, the appearance and the olfactory properties of nectarine slices during storage, while AIR samples showed symptoms of dehydration and browning. Sixty VOCs were identified in total in the headspace of the fresh nectarines and cold-stored fruit slices samples. Principal component anal. performed on VOCs allowed to differentiate fresh nectarines from cold-stored samples, with lactones and terpenes mainly related to fresh samples, and ester compounds pos. correlated to AIR or MAP samples. Partial least square regression models allowed to identify a pool of VOC predictors of olfactory sensory descriptors. In the experiment, the researchers used many compounds, for example, Isopentyl 3-methylbutanoate (cas: 659-70-1COA of Formula: C10H20O2).
