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, including apples, durians, pears, bananas, pineapples, and strawberries. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Recommanded Product: 4-Acetamidophenyl 2-acetoxybenzoate

Determination of residual solvents in Benorilate by headspace gas chromatography was written by Yang, Xujian;You, Qiuping;Huang, Yanna;Chen, Haitao;Chen, Zilong. And the article was included in Jinri Yaoxue in 2014.Recommanded Product: 4-Acetamidophenyl 2-acetoxybenzoate The following contents are mentioned in the article:

Objective: To establish a method of headspace gas chromatog. for the determination of the residual solvents in Benorilate. Methods: The Anal. Technol. AT · OV-1301 capillary column (30 m × 0.32 mm × 1.00 μm) with a flame ionization detector (FID) was adopted, and nitrogen gas was used as carrier. The temperatures of the injector inlet and the detector were set at 200°C and 250, resp. Split ratio was 2 : 1, and the flow rate was 1.0 mL/min. The column temperature was 100°C. Samples were equilibrated at 85°C for 30 min. External standard method was used with the dimethylacetylamide as solvent. Results: Excellent resolution and good linear calibration curves of the residual solvents were obtained. Conclusion: This accurate and sensitive method can be applied in the detection of residual solvents in Benorilate. This study involved multiple reactions and reactants, such as 4-Acetamidophenyl 2-acetoxybenzoate (cas: 5003-48-5Recommanded Product: 4-Acetamidophenyl 2-acetoxybenzoate).
