Ritalinic acid is a substituted phenethylamine and an inactive major metabolite of the psychostimulant drugs methylphenidate and ethylphenidate.[1][2] When administered orally, methylphenidate is extensively metabolized in the liver by hydrolysis of the ester group yielding ritalinic acid.[1] The hydrolysis was found to be catalyzed by carboxylesterase 1 (CES1).[3]

Uses

Ritalinic acid is used as an intermediate in the synthesis of methylphenidate and its analogues, such as ethylphenidate and isopropylphenidate.

gollark: Well, optionals should be clearly distinct from non-optional things, else badness occurs.

gollark: ```gostruct x { i int b bool}```or just the "yes you can make everything nil" thing.

gollark: By what specifically?

gollark: Optionals are NOT THE SAME TYPE Æ

gollark: Bad.
