Tetrolic acid, scientifically known as 2-butynoic acid (CAS 590-93-2), stands as a prominent molecule in the realm of organic chemistry. This short-chain unsaturated carboxylic acid, with its distinctive triple bond and carboxyl group, offers a versatile platform for a multitude of chemical transformations. As a fine chemical intermediate, its importance in various industrial and research applications cannot be overstated.

The chemical structure of tetrolic acid, CH3−C≡C−CO2H, provides chemists with two highly reactive sites: the internal alkyne and the carboxylic acid moiety. This dual functionality allows it to participate in a wide array of reactions, including additions across the triple bond, esterification, and amide formation, making it a cornerstone in the synthesis of more complex organic molecules. When considering the purchase of such a critical compound, identifying a reliable supplier for 2-butynoic acid is paramount to ensure the quality and consistency required for successful chemical endeavors.

For researchers and manufacturers seeking to buy 2-butynoic acid, understanding its properties is key. It is typically a white crystalline solid with a melting point range of 74-76°C and a boiling point of around 203°C. Its solubility in polar solvents like water and ethanol, coupled with its potential to sublime, dictates specific handling and storage procedures. For instance, optimal storage often involves sealed containers in a refrigerator due to its tendency to sublime at temperatures above 20°C.

The applications of tetrolic acid are diverse, spanning from its role in pharmaceutical intermediate synthesis to its use in material science and agrochemical development. Its ability to undergo various coupling reactions and functional group modifications makes it an indispensable tool for chemists aiming to construct intricate molecular architectures. Whether it's for the development of new drugs or advanced materials, the consistent supply of high-quality 2-butynoic acid is crucial. Sourcing this compound from reputable manufacturers in China ensures access to competitive pricing and adherence to international quality standards, facilitating innovation and efficient production.
