P-Aminobenzoic Acid (PABA), also known as Para-aminobenzoic acid or 4-Aminobenzoic acid, is a naturally occurring compound renowned for its versatile properties and critical roles across various industries. This vitamin-like substance is essential for the growth and division of certain microorganisms and holds significant value in human health and industrial applications. As a key aromatic amino acid, PABA plays an irreplaceable part in life's metabolic processes.

Physically, PABA presents as white or light yellow needle-like crystals or crystalline powder, which may turn slightly yellow upon exposure to air or light. It exhibits excellent solubility in hot water, ether, ethyl acetate, ethanol, and glacial acetic acid, while being insoluble in cold water, benzene, and petroleum ether. This distinct solubility profile makes it a valuable raw material for numerous chemical processes.

In the pharmaceutical sector, PABA serves as a vital intermediate. Notably, it is a key building block in the synthesis of folic acid, a crucial blood tonic. It is also used in the manufacture of coagulants and drugs intended for treating conditions such as rickets, rheumatic disease, arthritis, and tuberculosis. Its compatibility with certain antibiotics like penicillin or streptomycin has been observed to enhance their bacteriostatic effect, highlighting its potential in improving treatment outcomes.

Beyond pharmaceuticals, PABA finds extensive use in the cosmetic industry. It is a significant intermediate in the production of sunscreens, valued for its ability to absorb ultraviolet (UV) radiation, thereby offering skin protection. Additionally, it is explored in formulations aimed at promoting hair growth.

Furthermore, PABA is incorporated into nutritional products. As a component often associated with the Vitamin B complex (sometimes referred to as Vitamin B-100), it is recognized for its potential to support the body's metabolism, helping to combat fatigue and alleviate stress. It has also been studied for its ability to help relieve certain types of anemia.

Quality is paramount when sourcing raw materials, and PABA is available meeting stringent standards such as USP and BP. High-purity grades, typically with an assay of 98.0% to 102.0%, ensure suitability for sensitive applications like pharmaceuticals and cosmetics. The standard form is a solid powder, commonly packaged in 25kg drums for ease of transport and storage, requiring protection from light, dryness, and cool conditions to maintain stability over a typical shelf life of two years.

For businesses seeking a reliable source for high-quality P-Aminobenzoic Acid, understanding the supply chain is crucial. When considering a purchase, potential buyers often look for a reputable manufacturer or supplier capable of providing material that meets specific quality requirements and regulatory standards. Details regarding the current market price, available quantities, and logistical support are key considerations when looking to buy PABA. Inquiring directly with a trusted manufacturer or supplier is the most effective way to obtain detailed product specifications, pricing, and arrange for delivery. Whether for pharmaceutical synthesis, cosmetic formulation, or nutritional applications, sourcing PABA from an experienced manufacturer ensures access to a consistent and high-grade product.
