(R)-(+)-1,2,4-butanetriol - Introduction
(R)-( )-1,2,4-butanetriol is a colorless to slightly yellow solid with good solubility. It has a sweet taste and can be used as a substitute for food additives such as saccharin. In addition, it can also be used as an intermediate in organic synthesis for the synthesis of other compounds, such as dyes, drugs and fragrances. It can also be used as a raw material for the preparation of resins and plastics.
There are two main methods for preparing (R)-( )-1,2,4-butanetriol. One is obtained by a reduction reaction of sugar, for example, xylose is converted into 1,2, 4-butanetriol by a reduction reaction. The other is obtained by a cyclization reaction of 1,4-butanediol, for example, by an addition reaction of hydrogen bromide to give 1,3-butanediol, which is subsequently converted to 1,2, 4-butanetriol by an aldehyde condensation reaction.
Regarding safety information,(R)-( )-1,2,4-butanetriol is a relatively safe compound under normal use and storage conditions. However, it is still a chemical substance and should follow certain safe operating procedures. When contacting the compound, avoid direct contact with skin and eyes to avoid irritation. When using and storing, keep away from heat source and open flame to avoid burning and explosion. If ingested or inhaled, seek medical attention. In summary, when using and handling (R)-( )-1,2,4-butanetriol, safe operating procedures should be followed, and the compound should be stored and handled properly.
