4-Acetamidophenyl 2-acetoxybenzoate (cas: 5003-48-5) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Safety of 4-Acetamidophenyl 2-acetoxybenzoate

Rapid identification of 15 effective components of common cold medicine with MRM by LC-MS/MS was written by Jiang, Jian-guo;Zhang, Xi-ru;Zhang, Yi-hua;Song, Geng-shen. And the article was included in Yaoxue Xuebao in 2013.Safety of 4-Acetamidophenyl 2-acetoxybenzoate The following contents are mentioned in the article:

This paper reported the establishment of a method for rapid identification of 15 effective components of common cold medicine(paracetamol, aminophenazone, pseudoephedrine hydrochloride, methylephedrine hydrochloride, caffeine, amantadine hydrochloride, phenazone, guaifenesin, chlorphenamine maleate, dextromethorphan hydrobromide, diphenhydramine hydrochloride, promethazine hydrochloride, propyphenazone, benorilate and diclofenac sodium) with MRM by LC-MS/MS. The samples were extracted by methanol and were separated by a Altantis T3 column within 15 min with a gradient of acetonitrile-ammonium acetate(containing 0.25% glacial acetic acid), a tandem quadrupole mass spectrometer equipped with electrospray ionization source(ESI) was used in pos. ion mode, and multiple reaction monitoring(MRM) was performed for qual. anal. of these compounds The min. detectable quantity was 0.33-2.5μg·kg-1 of the 15 compounds The method is simple, accurate and has good reproducibility for rapid identification of many components in the same chromatog. condition, and provides a reference for qual. anal. of illegally added chems. in common cold medicine. This study involved multiple reactions and reactants, such as 4-Acetamidophenyl 2-acetoxybenzoate (cas: 5003-48-5Safety of 4-Acetamidophenyl 2-acetoxybenzoate).
