benorilate benorilate benorilate (inn), or benorylate, is an ester-linked codrug of aspirin with paracetamol. it is used as an anti-inflammatory and antipyretic medication. in the treatment of childhood fever, it has been shown to be inferior to paracetamol and aspirin taken separately. in addition, because it is converted to aspirin, benorylate is not recommended in children due to concerns about reye syndrome. benorilateclinical dataroutes ofadministrationoralatc coden02ba10 (who) identifiers iupac name 4-acetamidophenyl 2-(acetyloxy)benzoate cas number5003-48-5 npubchem cid21102chemspider19846 nuniiw1qx9dv96gchemblchembl162036 ncomptox dashboard (epa)dtxsid5022649 echa infocard100.023.340 chemical and physical dataformulac17h15no5molar mass313.309 g·mol−13d model (jsmol)interactive image smiles o=c(c)oc2ccccc2c(=o)oc1ccc(nc(c)=o)cc1 inchi inchi=1s/c17h15no5/c1-11(19)18-13-7-9-14(10-8-13)23-17(21)15-5-3-4-6-16(15)22-12(2)20/h3-10h,1-2h3,(h,18,19) nkey:fejklnwaoxssnr-uhfffaoysa-n n ny (what is this?)
