For chemists engaged in intricate organic synthesis, understanding the detailed properties of chemical building blocks is fundamental to success. 5-Methylisoxazole-3-carboxylic acid (CAS: 3405-77-4) is one such compound, notable for its distinctive isoxazole heterocyclic ring system and a reactive carboxylic acid functional group. These features contribute to its versatility as an intermediate in the creation of complex organic molecules, finding applications in both pharmaceutical and agrochemical research.

The molecular structure of 5-Methylisoxazole-3-carboxylic acid (C5H5NO3, MW: 127.098) dictates its chemical behavior. The isoxazole ring, a five-membered heterocycle containing adjacent nitrogen and oxygen atoms, imparts specific electronic and steric properties. The methyl group at the 5-position and the carboxylic acid at the 3-position are sites for further chemical transformation. When you buy 5-methylisoxazole-3-carboxylic acid, you are acquiring a compound that can undergo various reactions typical of carboxylic acids, such as esterification, amidation, and decarboxylation. The heterocyclic ring itself can also participate in certain reactions, offering diverse synthetic pathways.

A crucial aspect for any researcher or procurement specialist is sourcing this compound with guaranteed purity. High-quality organic synthesis building blocks are essential for reproducible experimental results. Therefore, when you identify a manufacturer or supplier, always verify the purity specifications, typically offered at 98% or higher. The appearance is usually described as a pale yellow powder. Understanding the optimal conditions for storage and handling, as indicated by the supplier's Safety Data Sheet, is also vital.
