Application
(R)-3-Hydroxybutyric acid may be used in the preparation of copolymers by reacting with various hydroxyalkanoic acids.1 It may also be used in the preparation of (3R,4R)-4-acetoxy-3-[(R)-1-(formyloxy)ethyl]-2-azetidinone.2
Other Notes
Important chiral starting material; enantioselective reactions at the 2-, 3- and 4-positions via the cyclic acetal with aldehydes; preparation of (R)-β-butyrolactone.

お世話なっております。基本的な質問ですみません。LC-MSMS分析の標品、定量目的として使用したいと考えております。注文済みではありますがまだ納品はされておりまｓん。到着後保存は冷蔵庫でする予定ですが、秤量するなどのときに長時間室温に置いて置いたりすると、３HBが重合してしまうことはありますか？(２量体や３量体などになってしまうことはありますか？）

This product has not been tested for the suitability oincell culture. The (R)-3-Hydroxybutyric acid is more often used in the preparation of copolymers or in the preparation of (3R,4R)-4-acetoxy-3-[(R)-1-(formyloxy)ethyl]-2-azetidinone. This product would have to be validated for use in any in vitro applications such as cell culture. Our product H6501, DL-B-Hydroxybutyric acid sodium salt, while also not tested for use in culture, is more frequently used for in vitro studies. Please see the product detail page for product H6501: https://www.sigmaaldrich.com/product/sigma/h6501.
