3-甲氧基-4-羟基扁桃酸是制备新型广谱抗菌药物甲氧苄胺嘧啶和香草醛的重要中间体，3-乙氧基-4羟基扁桃酸是制备乙氧基香草醛的中间体。香兰素或乙基香兰素为广谱香料，可用作定香剂、调味剂和变味剂。3-甲氧基-4-羟基扁桃酸是制备新型广谱抗菌药物甲氧苄胺嘧啶和香草醛的重要中间体。Vanillylmandelic acid (VMA)是合成人工香草调味料的中间物，是儿茶酚胺的终末期代谢物。
Vanillylmandelic acid has antioxidant activity, the IC 50 value is determined as the amount of VMA required to reduce 50% of the starting concentration of free radical is 33*10 -6 M in the UV-Vis decolourisation DPPH assay.
Vanillylmandelic acid (intra-arterial injection over 1 min; 1, 10 and 100 mg/kg; the 60 min-observation period) produces a significant difference between vanillylmandelic acid groups and controls. Vanillylmandelic acid decreases the heart rate by 17.5%, 17.9% and 18.9% after 1, 10 and 100 mg/kg, respectively. Mean blood pressure is decreased by 13.5% in control animals as compared to 37%, 23% and 26% after 1, 10 and 100 mg/kg, respectively, in wistar rats.
