Phthalide Usage And Synthesis

Chemical Properties	WHITE TO LIGHT BEIGE CRYSTALLINE POWDER
Chemical Properties	White powder; sweet tonka, coumarin, powdery, coconut, phenolic, lactonic aroma.
Definition	ChEBI: A gamma-lactone that is 1,3-dihydro-2-benzofuran in which the hydrogens at position 1 are replaced by an oxo group.
Aroma threshold values	Low strength odor, Tonka type.
Taste threshold values	Sweet coumarin, coconut, creamy, anisic, green vegetable, floral taste at 100 ppm in water.
Enzyme inhibitor	This lactone on the above left (FW = 134.13 g/mol; CAS 87-41-2; M.P. = 72-74°C) reportedly inhibits chymotrypsin. Phthalide is a fungicide that inhibits melanin biosynthesis and has been used in the treatment of rice blast disease. Note: The term phthalide has also been used to refer to the tetrachloro derivative (i.e., 4,5,6,7-tetrachorophthalide (on the right above); FW = 271.91 g/mol; CAS: 27355-22-2; also known as BAYER 96610, KF- 32, Rabcide, and TCP). Target(s): chymotrypsin; scytalone dehydratase, inhibited by the tetrachloride derivative; and trihydroxynaphthalene reductase, inhibited by the tetrachloride derivative.
Purification Methods	Crystallise phthalide from water (75mL/g) and dry it in air on filter paper. [Beilstein 17/10 V 7.]
