Description

Generic Name:
PHTHALIDE FOR SYNTHESIS
Product Description:
Phthalide is an organic chemical compound with the molecular formula C8H602. lt is a lactone thatserves as the core chemical structure for a variety of more complex chemical compounds includingdyes (such as phenolphthalein), fungicides (such as tetrachlorophthalide, often referred to simplyas “phthalide”), and natural oils (such as butylphthalide).
Product Application:
Phthalide is used in the synthesis of several pharmaceutical drugs including isoxepac, vatalanib,and hydralazine as well as the pesticide kresoxim-methyl .
Product Procedure:
administered for three days at doses of 10 or 40
Product Note:
1. In checking these directions complete failure was repeatedly encountered with good commerciagrades of zinc dust, and only when the metal was activated with copper sulfate did reductionoroceed at all.
2, The mother liquor, on concentrating to less than half its volume, yields no further crystals onchilling
3. On cooling, a minute amount of a yellow impurity separates with the phthalide at the beginningof crystallization. This impurity apparently cannot be eliminated by boiling with charcoal but ispresent in too small amount to affect the melting point of the product.
4. Concentration of the final mother liquor to a volume of 500 cc. yields a further small quantity ofphthalide, but this operation is scarcely worth while.
