Ritalinic acid (Cat No.: M080742) is a primary metabolite of methylphenidate, the active ingredient in medications like Ritalin used to treat ADHD and narcolepsy. Chemically known as α-phenyl-2-piperidineacetic acid, it results from hydrolysis of the methyl ester group in methylphenidate. This white crystalline solid is pharmacologically inactive but serves as an important biomarker in drug metabolism and pharmacokinetics studies. Ritalinic acid is also used in forensic toxicology and research to monitor therapeutic drug levels and investigate metabolic pathways of central nervous system stimulants.
