Bulk Active Pharmaceutical Ingredient (API) Sources for: Valproic Acid

Last updated: July 30, 2025

Introduction

Valproic acid (VPA) is a widely utilized anticonvulsant and mood-stabilizing agent. Its applications span the treatment of epilepsy, bipolar disorder, and migraine prophylaxis. The global demand for VPA necessitates reliable bulk API sources characterized by quality, consistency, and regulatory compliance. This article examines prominent suppliers of bulk valproic acid, evaluates their market positioning, and provides insights for pharmaceutical companies seeking to secure dependable API sources.

Understanding Valproic Acid Production

Valproic acid is synthesized predominantly through chemical processes involving the degradation of valproates or via direct synthesis routes. The manufacturing requirements demand strict control over impurity profiles to adhere to regulatory standards, notably those stipulated by the FDA, EMA, and other health authorities.
