Cas no 1694-82-2 (cis-4-Methyl-1,2-3,6-tetrahydrophthalic Anhydride)

Technical Introduction: cis-4-Methyl-1,2-3,6-tetrahydrophthalic Anhydride cis-4-Methyl-1,2-3,6-tetrahydrophthalic anhydride is a cyclic anhydride derivative used primarily as a reactive intermediate in organic synthesis and polymer chemistry. Its strained ring structure and anhydride functionality make it a valuable building block for the preparation of resins, epoxy curing agents, and specialty polymers. The compound exhibits enhanced reactivity due to the presence of the methyl group, which can influence steric and electronic properties in downstream applications. It is particularly useful in formulations requiring controlled cross-linking or tailored thermal and mechanical properties. The product is typically handled under anhydrous conditions to preserve its reactivity.
