Isopentyl hexanoate (cas: 2198-61-0) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. 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.

Wuyi rock tea (WRT), is one kind of oolong tea and widely appreciated for its typical ′rock flavorâ€? The odor characteristics of WRT during processing were comprehensive investigated by gas chromatog.-mass spectrometry, sensory evaluation and odor activity value (OAV). Alcs., alkenes and esters were the main volatiles formed during tea processes, but the WRT contained more heterocyclic compounds, among which 15 N-containing volatiles were newly identified in this study, accounting for 60.52% of total amounts of volatiles in WRT. In response, the original green and chem. odors converted to roasted and woody odors, and full fire processing was effective to enhance roasted, floral and woody odors, weaken chem. odor. 2-Ethyl-3,5-dimethylpyrazine (OAV 4.71) was confirmed as the aroma-active compound of WRT with roasted odor by aroma recombination experiment In addition, strong roasted, floral and moderate woody odors were perceived as the outline of ′rock flavorâ€?in WRT aroma. These results provide theor. basis for processing and quality control of WRT. This study involved multiple reactions and reactants, such as Isopentyl hexanoate (cas: 2198-61-0Product Details of 2198-61-0).
