In an article, author is Liu, Honglei, once mentioned the application of 7507-86-0, COA of Formula: https://www.ambeed.com/products/7507-86-0.html, Name is 2-Bromo-5-methoxybenzaldehyde, molecular formula is C8H7BrO2, molecular weight is 215.04, MDL number is MFCD00463817, category is phthalazine. Now introduce a scientific discovery about this category.
The Sc(OTf)(3)-catalyzed diastereoselective [3 + 3] cycloaddition of phthalazinium dicyanomethanides with cyclopropane 1,1-diesters proceeded smoothly under mild reaction conditions, affording a variety of 3,4-dihydro-1H-pyrido[2,1-a]phthalazine derivatives in up to 99% yields with excellent diastereoselectivities.
If you are interested in 7507-86-0, you can contact me at any time and look forward to more communication. COA of Formula: https://www.ambeed.com/products/7507-86-0.html.
