Description

4-Aminobenzoic Acid Sodium Salt is the water-soluble sodium salt of para-aminobenzoic acid (PABA), a key organic intermediate. This compound is valued for its enhanced stability and solubility profile compared to the free acid, facilitating its use in various synthesis and formulation processes. It serves as a critical building block for manufacturers in the pharmaceutical, cosmetic, and specialty chemical industries seeking reliable, high-purity raw materials.

Application

• Pharmaceutical Synthesis: Acts as a key intermediate in the production of local anesthetics (e.g., procaine), folic acid analogs, and other active pharmaceutical ingredients (APIs).
• UV-Absorbing Agents: Used in the formulation of sunscreen lotions, creams, and cosmetic products for its ability to absorb ultraviolet light.
• Biochemical Research: Employed as a precursor or reagent in microbiological media and biochemical studies, particularly concerning vitamin biosynthesis.
• Dye and Pigment Intermediate: Serves as a starting material in the synthesis of azo dyes and other organic colorants.
• Crosslinking Agent: Utilized in the production of certain polymers and resins where its amine and carboxylate functionalities can participate in reactions.
• Feed Additive Precursor: Can be processed into forms used in animal nutrition, contributing to metabolic functions.

Quality Control

Our 4-Aminobenzoic Acid Sodium Salt is manufactured under a strict quality management system. Each batch is tested to ensure it meets high-purity standards suitable for pharmaceutical and cosmetic applications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
