Isopentyl hexanoate (cas: 2198-61-0) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. 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. HPLC of Formula: 2198-61-0

Effects of processes involving low-temperature and low-oxygen concentrations on the quality and aroma of apple juice was written by Lu, Yao;Zhang, Kai-jie;Li, Gen;Zhao, Yan;Ding, Chen;Ma, Yin-fei;He, Fa-tao;Zhu, Feng-tao;Chu, Le.

Apple juice was prepared from Fuji apples using three different processes. The basic index, antioxidant activity, and aroma characteristics of the three juices were analyzed. Results revealed that the NFC juice contained more active ingredients and exhibited better aroma characteristics than the FC juice. Because of the requirement of low temperature and shorter processing time, the low-temperature-hypoxia NFC juice contained more active ingredients than the traditional NFC juice. The total phenol content of low-temperature-hypoxia NFC juice was 626.74 mg/L, which was significantly higher than that of the traditional NFC juice (P<0.05). The aroma of fresh apples was maintained by the low-temperature-hypoxia NFC juice (total content volatile component, 133.02 mg/L). This juice also exhibited less bad flavor than juices prepared using the other two processes. This study involved multiple reactions and reactants, such as Isopentyl hexanoate (cas: 2198-61-0HPLC of Formula: 2198-61-0).
