Salicylic Acid-d4

Salicylic acid-d4 is intended for use as an internal standard for the quantification of salicylic acid by GC- or LC-MS. Salicylic acid is an active metabolite of the COX inhibitor aspirin (Cay-70260) and a plant hormone that has been found in Cucumis sativus. It protects Cucumis sativus leaves from infection by S. fuliginea or E. cichoracearum when used at a concentration of 10 mM, as well as inhibits A. thaliana root growth at 0.3 mM. Salicylic acid (1 and 4 mM) reduces IFN-gamma- and TNF-alpha-induced increases in NOS2 expression in primary rat cardiac fibroblasts. It decreases urine prostaglandin E2 (PGE2, Cay-14010) levels in dogs when administered at a dose of 40 mg/kg.Formal Name: 6-hydroxy-benzoic-2,3,4,5-d4 acid. CAS Number: 78646-17-0.
