Description

n-Propyl 4-Aminobenzoate is a benzoate ester derivative of para-aminobenzoic acid (PABA). This compound is valued for its role as a versatile chemical intermediate and UV-absorbing chromophore in advanced formulations. It is primarily utilized by manufacturers in the pharmaceutical, personal care, and specialty chemical industries for synthesizing active ingredients and functional additives.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of local anesthetic agents and other active pharmaceutical ingredients (APIs).
• UV Filter / Sunscreen Agent: Used in the formulation of sun care products for its ability to absorb ultraviolet radiation.
• Polymer & Resin Modifier: Acts as a light stabilizer or additive in specialty polymers to enhance durability against UV degradation.
• Organic Synthesis: Serves as a protected intermediate or reagent in multi-step synthetic routes for fine chemicals.
• Cosmetic Ingredient: Employed in skincare formulations where UV protection and stabilization are required.
• Research & Development: Used in laboratory settings for chemical research, method development, and analytical standards.
