42177-25-3 - Introduction
(R)-( )-1-(1-naphthyl)ethanol, also known as (R)-( )-1-(1-naphthyl)ethanol, is a chiral compound. Its chemical formula is C12H12O and its relative molecular mass is 172.22g/mol. It is a solid, usually in the form of white to pale yellow crystals.
One of the main applications of (R)-( )-1-(1-naphthyl)ethanol is as a chiral inducer. It is often used to catalyze asymmetric reactions in organic synthesis, especially asymmetric hydrogenation and asymmetric nucleophilic addition reactions. Due to its chirality, highly enantioselective products can be obtained with it. In addition, it can also be used as a synthetic intermediate for the construction of chiral drugs and natural products.
Methods for preparing (R)-( )-1-(1-napthyl) ethanol include asymmetric synthesis and resolution methods. One commonly used method of preparation is the reduction of an enantiomeric asymmetric phosphoramidite to the (R)-(+)-1-(1-naphthyl)ethanol by asymmetric hydrogenation with the aid of a chiral catalyst.
Regarding the safety information of the (R)-( )-1-(1-naphthyl)ethanol, it is considered relatively safe under normal handling and use conditions. However, it may be irritating to the skin, eyes and respiratory tract, so appropriate personal protective equipment should be worn during operation. In addition, it should be stored in a dry, cool, well-ventilated place, and stored separately from oxidants and strong acids. Any operation involving (R)-( )-1-(1-napthyl) ethanol should be performed under safe laboratory conditions. Before using or handling (R)-( )-1-(1-naphthyl)ethanol, carefully read and follow relevant safety precautions and operating instructions.
