- n. A colorless gas (NH2CH3), having a strong ammoniacal odor, and resembling ammonia in many of its reactions. It may be regarded as ammonia (NH3) in which the radical methyl (CH3) has been substituted for a hydrogen atom. When brought in contact with a lighted taper it burns with a livid yellowish flame.
