Sodium triacetoxyborohydride, also known as NaBH(OAc)3, is a white to off-white crystalline solid with the chemical formula C6H9BNaO6. It is a mild and selective reducing agent commonly used in organic synthesis for the reduction of various functional groups, such as aldehydes, ketones, imines, and alkyl halides. Sodium triacetoxyborohydride exhibits good stability in aqueous and alcoholic solutions and is relatively safe to handle compared to other reducing agents.
