Description

4-Aminobenzoic Acid, Sodium Salt Hydrate is a high-purity, water-soluble derivative of para-aminobenzoic acid (PABA), offered at a minimum purity of 99%. This compound serves as a critical intermediate and active ingredient in advanced pharmaceutical synthesis and specialty chemical manufacturing. It is essential for industries requiring a stable, bioavailable form of PABA for applications in UV protection, vitamin B complex synthesis, and microbiological research.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of folic acid analogs, local anesthetics (e.g., procaine), and sunscreening agents.
• UV Absorber & Sunscreen Agent: Used in the formulation of cosmetic and dermatological products for its ability to absorb ultraviolet B (UVB) radiation.
• Microbiological Culture Media: Essential component in certain culture media, serving as a growth factor for microorganisms.
• Biochemical Research: Utilized as a substrate or standard in enzymatic studies and metabolic pathway research.
• Chemical Synthesis: Acts as a versatile precursor for azo dyes, liquid crystal materials, and other fine chemicals.
• Vitamin B Complex Factor: Employed in nutritional supplements and fortification processes.

Quality Control

Our 4-Aminobenzoic Acid, Sodium Salt Hydrate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets the 99% minimum purity specification and is free from unacceptable levels of impurities. While not currently USP/EP grade, production can adhere to cGMP principles for relevant applications. A comprehensive Certificate of Analysis (COA) detailing identity, assay, impurity profile, and residual solvents is provided with every shipment.

Storage

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