4-Acetamidophenyl 2-acetoxybenzoate (cas: 5003-48-5) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. 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. Formula: C17H15NO5

Determination of Benorilate Dispersible Tablets by HPLC was written by Cheng, Zheng;You, Yu-zhou;Xing, Jian-hui;Liu, Hu. And the article was included in Guangzhou Huagong in 2016.Formula: C17H15NO5 The following contents are mentioned in the article:

A method for determination of Benorilate Dispersible Tablets by HPLC was established. Ultimate XB-C18 column (250 mm×4.6 mm×5μm) was used, the mobile phases consisted of methanol and water (60:40), the detection wavelength was at 240 nm, the column temperature was 30°C, the flow rate was 1 mL/min. Results showed that the linear range of benorilate was at 4.96-118.92 mg/mL, r = 0.99989. The average recovery was 99.47%, RSD = 0.21% (n = 6). The method was accurate. It could be used for determination of Benorilate Dispersible Tablets. This study involved multiple reactions and reactants, such as 4-Acetamidophenyl 2-acetoxybenzoate (cas: 5003-48-5Formula: C17H15NO5).
