Appearance: colorless or light yellow liquid Boiling point: 140-141 °C (lit.) Relative density (water = 1): 0.9355 g/cm3 Assay: ≥98% Uses: It is a useful synthetic intermediate. It is used in the synthesis of diketopiperazine as a potent and selective oxytocin antagonist. It can also be used in the preparation of dihydroquinazolimide with anti-inflammatory activity.
Appearance: colorless liquid. Boiling point: 116-118 °C Relative density (water = 1): 0.9355 g/cm3 Assay: ≥98% Uses: can be used as pharmaceutical and pesticide intermediates
Appearance: colorless liquid. Boiling point: 98-101 °C (lit.) Relative density (water = 1): 0.938 g/mL at 25 °C (lit.) Solubility: soluble in water Assay: ≥98% Uses: For the preparation of cyclic tetrapropyltetrahydronaphthone, it is necessary to undergo enantiomeric-selective palladium-catalyzed cycloaddition reaction. It is also a common reagent for the introduction of cyclopropyl in synthesis.
