Salts and Derivatives of Active Pharmaceutical Ingredients (API)
The salts of Active Pharmaceutical Ingredients (APIs) are compounds formed by the reaction of an acid with a base, resulting in an ionic equilibrium. These salts often improve the solubility and stability of APIs, facilitating their absorption in the body. API derivatives are chemical variants of an active ingredient that may have enhanced or modified properties to optimise therapeutic efficacy. API salts are used in the formulation of oral, injectable, and topical medications. Additionally, API derivatives can improve the pharmacokinetics of drugs, such as enabling controlled release of active substances.
At CymitQuimica, we provide API salts and derivatives with the necessary purity and quality for research and pharmaceutical formulation development.
