1. 2-Butynoic acid CAS 590-93-2 is widely used as a key intermediate in organic synthesis, particularly for constructing complex molecules like pharmaceuticals, agrochemicals, and specialty polymers. Its terminal alkyne and carboxylic acid groups enable versatile reactions (e.g., alkynylation, esterification) to introduce functional moieties into target compounds.
2. 2-Butynoic acid serves as a building block in the synthesis of fine chemicals, such as flavor and fragrance ingredients or chiral ligands. Its unique structure (a four-carbon chain with a triple bond and a carboxyl group) allows for the creation of molecules with specific sensory or catalytic properties.
3. In research settings, 2-Butynoic acid CAS 590-93-2 is used to study reaction mechanisms involving alkynes and carboxylic acids, and as a monomer to prepare functional polymers (e.g., those with tunable thermal or chemical stability) for materials science applications.
Packed in 25 kg per drum or based on customers' requirements.
1. Store 2-Butynoic acid CAS 590-93-2 in a tightly sealed, chemically resistant container (e.g., amber glass or HDPE plastic) to prevent evaporation and contamination—its carboxylic acid group can react with moisture or air over time, reducing purity for synthesis use.
2. Keep the container in a cool, dark area away from direct sunlight and heat sources (e.g., lab hotplates, radiators). High temperatures may accelerate decomposition or increase volatility, compromising its effectiveness as an organic intermediate.
3. Store 2-Butynoic acid CAS 590-93-2 separately from strong bases, oxidizers, and reactive metals to avoid unwanted reactions (e.g., neutralization or hazardous byproduct formation). Label the container clearly with its name and handle with care (it may be corrosive), keeping 2-Butynoic acid out of reach of children and unauthorized personnel.
