P-AMINOBENZOIC ACID POTASSIUM SALT CAS:138-84-1

p-Aminobenzoic acid potassium salt (C7H8KNO2) is an important derivative of p-aminobenzoic acid (PABA), which has garnered attention for its varied applications in medicine and cosmetics. The compound is formed by neutralizing p-aminobenzoic acid with potassium hydroxide, resulting in a stable, water-soluble salt. The presence of an amino group (-NH2) and a carboxylic group (-COOH) on the aromatic ring endows K-PABA with several significant chemical properties. One of the primary applications of potassium p-aminobenzoate is in the pharmaceutical industry, where it serves as a key intermediate in synthesizing various drugs. PABA itself plays a crucial role in the biosynthesis of folate, an essential vitamin for human health, thereby contributing to cell growth and repair. Additionally, K-PABA has been studied for its potential therapeutic effects, including anti-inflammatory and analgesic properties, making it a subject of interest in drug development. Another notable application of K-PABA is in the cosmetic industry, particularly as an active ingredient in sunscreen formulations. Due to its ability to absorb UV radiation, potassium p-aminobenzoate helps protect the skin from harmful sun exposure, preventing sunburn and reducing the risk of skin cancer. Its incorporation into topical products underscores its importance in personal care and dermatological treatments. Furthermore, the compound's solubility in water allows for easy incorporation into aqueous formulations, enhancing its versatility in different applications. Research into K-PABA continues to explore its safety profile and efficacy, especially regarding potential allergic reactions associated with its use in cosmetics. Understanding these aspects is crucial for ensuring consumer safety and regulatory compliance. Overall, potassium p-aminobenzoate represents a vital compound that bridges the fields of chemistry, pharmaceuticals, and cosmetics, highlighting its multifaceted utility in modern science and industry.
