methyl 3-benzoylpropionate CAS No.:103-25-3Properties: 45.65Purity:99%Packaging: 200kg blue barrelStorage method:dry and coldStorage method: Room temperature, away from light, cool and dry place, sealed and storedUsage：It is used to synthesize methyl p-sulfonyl chlorobenzopropionate. Aromatic sulfonyl chloride is an important pharmaceutical intermediate (synthetic sulfonamide drugs), which has a broad application prospect. The synthesis of p-sulfonyl chlorobenzopropionate by methyl phenylpropionate is simple and practical. The technical scheme adopted in the invention for the above purposes is as follows: the synthesis method of methyl sulfonyl chlorobenzopropionate is firstly esterified with phenylpropionate, then sulfonated with chlorosulfonic acid, then hydrolyzed, the solid is precipitated, dried, recrystallized and refined as the product.
