 2,3-Butanediol,(2S,3S)- , its cas register number is 19132-06-0. It also can be called (2S,3S)-2,3-Butanediol ; (2S,3S)-Butan-2,3-diol ; and (2S,3S)-Butane-2,3-diol .
 2,3-Butanediol,(2S,3S)- (CAS NO.19132-06-0) could be stable under normal temperatures and pressures. It should avoid the condition like incompatible materials, exposure to air, contact with water. It is not compatible with other materials contact with water, reducing agents, acid chlorides, acid anhydrides, chloroformates. And also prevent it to broken down into hazardous decomposition products: carbon monoxide, carbon dioxide. However, its hazardous polymerization will not occur.
