4-Fluoromethylphenidate (commonly known as 4F-MPH) is a novel synthetic stimulant of the substituted phenethylamine and piperidine classes. Thus, it produces long-lasting euphoriant, and
stimulating effects when administered. It is a related structural analog of the commonly prescribed ADHD drug methylphenidate (known by the brand-names Ritalin and Concerta).
