2280-27-5 - Introduction

S)-( )-acid is a chiral compound with the chemical formula C5H11NO3 and its structural formula is as follows:

H
|
H3C - C - CH3
| |
HO NH2
The compound is an amino acid, also known as lysine (Leucine). It is one of the eight essential amino acids that the body needs and can be obtained from proteins. Lysine is a basic component of muscle tissue and protein, and is very important for maintaining normal protein metabolism and health in the human body.

Regarding the preparation method of (S)-( )-0.acid, a commonly used method is to obtain it through chemical synthesis. Specifically, it can be prepared by the phthalic anhydride acylation reaction of L-oxaloacetic acid (L-Ketoisocaproic acid) and the reaction of amino acetic acid (aminoacetic acid).

Regarding safety information, lysine belongs to agricultural products and is safe for consumption. However, for the safety of (S)-( )-acid obtained by chemical synthesis, further experiments and studies are needed to evaluate its toxicity and safety. When using this compound, the safe handling of chemicals should be observed, and direct contact with skin, eyes or mucous membranes should be avoided. Seek immediate medical help in case of accidental contact or ingestion. This information is for reference only, and specific safety information needs to be evaluated based on relevant chemical substance data and experimental results.
