Linear alkyl benzene sulfonic acid

Linear Alkyl Benzene Sulfonic Acid (LABSA) is a strong organic sulfonic acid widely used in pharmaceutical and laboratory applications as an acidifying agent, pH regulator, and surfactant. It is a viscous, strongly acidic liquid that is highly soluble in water and suitable for preparing standardized acidic solutions for analytical and experimental purposes.

🏭⚗️ Production
LABSA is produced by sulfonation of linear alkyl benzene with concentrated sulfuric acid under controlled conditions. For pharmaceutical and laboratory applications, the product can be further purified or diluted to produce stable, high-quality solutions that maintain effective acidifying and emulsifying properties suitable for experimental and analytical work.

🔬 Properties
LABSA is a clear to slightly brown viscous liquid with a pungent acidic odor. It forms strongly acidic aqueous solutions that are chemically stable under recommended storage conditions. The solution exhibits reliable pH regulation and emulsifying capacity, making it suitable for precise experimental formulations, buffer preparations, and chemical reactions requiring strongly acidic conditions.

🧪 Applications
In pharmaceutical and laboratory settings, LABSA is used as a pH regulator and acidifying agent in buffer solutions, titrations, and controlled chemical reactions. It also serves as a surfactant in experimental formulations requiring controlled emulsification and as a reagent in analytical chemistry to create acidic media or to test solubility and reactivity under strongly acidic conditions.

⚠️ Safety
LABSA is highly corrosive and can cause severe irritation or burns to skin, eyes, and mucous membranes. Protective gloves, goggles, and lab coats should be worn during handling. The solution should be stored in tightly closed containers, away from oxidizers and heat sources, in a cool, well-ventilated area to ensure stability and safety.
