Cyclopentanecarboxylic acid, 3-amino-, (1R,3S)- (9CI) - Introduction

(1R,3S)-I acid, also known as (1R,3S)-I acid, is an organic compound. Its chemical formula is C6H11NO2, and its structure contains a cyclopentane ring, in which an amino group and a carboxyl group are attached to carbon 1 and carbon 3, respectively.

(1R,3S)-acid is a chiral compound, that is, it has multiple stereoisomers. Among them, the isomer of (1R,3S) is its most common form.

Regarding the nature,(1R,3S)-acid is a white crystalline solid, soluble in water and some organic solvents. It is a weakly acidic substance that can react with a base to form the corresponding salt. It is stable at room temperature, but should avoid prolonged exposure to light and moisture.

This compound has certain applications in medicinal chemistry. For example, it can be used as a building block for alkaloids and also for the synthesis of biologically active compounds. In addition, it can also be used as a catalyst ligand for chiral identification reactions in organic synthesis.

The method of preparing (1R,3S)-and acid can be done in a variety of ways. A common method is to react the halogenated hydrocarbon on the cyclopentane ring with ammonia to form the corresponding amino compound. Then, the target product is obtained by an acid treatment and a crystallization purification step.

Regarding safety information,(1R,3S)-acidid is generally relatively safe under normal use conditions. However, as with any chemical substance, users should follow proper operating procedures and safety measures, such as wearing suitable personal protective equipment (such as gloves, glasses, etc.) and avoiding swallowing or direct contact with skin and eyes. In addition, the compound should be stored and handled properly to avoid mixing with incompatible substances and to prevent ignition and high temperatures.
