Chemical Properties

Formula Weight
Moisture Sensitive


A series of novel five-membered urea derivatives as potent NK1 receptor antagonists is described. The effects of substitution of a 4-fluoro group at the phenyl ring and the introduction of an α-methyl group at the benzylic position to improve potency was found. 3,5-Bis(trifluoromethyl)benzyl bromide has been used as derivatization reagent in detection of uracil in DNA by GC and negative chemical ionization mass spectrometry.


Moisture Sensitive. Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Store away from strong oxidizing agents, moisture, water.
