Description
Paroxetine Base Product Overview
Paroxetine base (C19H20FNO3) is the (3S,4R)-enantiomer of the free amine. It is an oily to waxy material or solid that is practically insoluble in water. In medicines, paroxetine is almost always used as a salt.
API producers use the base to make salts such as Paroxetine Hydrochloride and paroxetine mesylate (CAS 217797-14-3), which have better stability and handling properties. Formulation scientists also use it in development work, for example for transdermal and other non-standard dosage forms, and analytical laboratories use it as a reference material.
Zyntex supplies paroxetine base only to licensed pharmaceutical companies and laboratories. Related SSRIs in our range include Sertraline Hydrochloride and Fluoxetine Hydrochloride.
