| 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.] |
