Butanoic Acid Extra Pure
Original price was: $ 35.00.$ 34.78Current price is: $ 34.78.
Butanoic Acid Extra Pure, also known as butyric acid, is a high-purity carboxylic acid used in laboratory research for organic synthesis, esterification studies, and biochemical analysis. It serves as a building block in the preparation of esters, polymers, and pharmaceuticals, and is also studied for its role in metabolic and microbial pathways. With its strong, characteristic odor and reactive carboxyl group, it is valuable in reaction mechanism investigations and as a standard in acid-base titrations. The extra pure grade ensures low levels of moisture and contaminants, offering consistent performance in sensitive experiments. It should be handled in well-ventilated areas and stored in tightly sealed containers, away from heat and oxidizing agents.
