2,2-Dimethylbut-3-enoic acid (98%, stabilized with MEHQ) features a conjugated enoic system flanked by two methyl groups at C2, enhancing stability and enabling direct use in Diels-Alder cycloadditions. The MEHQ stabilizer suppresses polymerization under ambient conditions, ensuring reliable performance in synthetic workflows.
2,2-Dimethylbut-3-enoic acid (98%, stabilized with MEHQ) serves as a versatile building block for α,β-unsaturated carboxylic acids, enabling efficient Michael additions and Diels-Alder reactions. Its conjugated enoic acid structure offers enhanced stability under standard storage conditions due to MEHQ-mediated radical inhibition. The molecule exhibits excellent bench stability, facilitates straightforward purification via recrystallization, and demonstrates broad functional group tolerance in synthetic workflows involving heterocycle formation and peptide side-chain modifications.
