⚗️ Chemical & Physical Properties
L-kynurenine is a white solid with a faint odor. Its appearance is crystalline and powdery.
With a molar mass of 209.24 g/mol and a density of 1.52 g/cm^3, L-kynurenine is comparable in molar mass to common food items such as glucose (180.16 g/mol) and in density to water (1 g/cm^3).
L-kynurenine has a melting point of 192-195°C and a boiling point of 830°C. These values are much higher than those of common food items, where melting points typically range from 0-100°C and boiling points rarely exceed 100°C.
L-kynurenine is sparingly soluble in water and exhibits low viscosity. This contrasts with common food items such as sugar and salt, which are highly soluble in water and have a higher viscosity.
🏭 Production & Procurement
L-Kynurenine is primarily produced through the enzymatic degradation of the amino acid tryptophan by the enzyme tryptophan 2,3-dioxygenase or indoleamine 2,3-dioxygenase. This process leads to the formation of L-kynurenine as one of the metabolites along the kynurenine pathway.
The procurement of L-kynurenine for research or pharmaceutical purposes involves its extraction from biological sources such as mammalian tissues, bacteria, or yeast cultures where the kynurenine pathway is active. Once extracted, L-kynurenine can be purified through various chromatography techniques to obtain a high level of purity suitable for use in experiments or drug development.
L-Kynurenine can be transported and stored in its crystalline form or as a solution in a solvent such as dimethyl sulfoxide (DMSO) to prevent degradation and maintain stability during transit. Proper labeling and documentation of the substance must be provided to comply with regulations for the shipping and handling of potentially hazardous or controlled compounds.
⚠️ Safety Considerations
Safety considerations for L-kynurenine must be taken into account due to its potential hazards. As a chemical compound, L-kynurenine can pose health risks if not handled properly. It is important to wear appropriate personal protective equipment, such as gloves and goggles, when working with L-kynurenine to prevent skin and eye irritation. Additionally, proper ventilation should be ensured to avoid inhalation of the substance, which can cause respiratory discomfort. Overall, safe handling practices should be followed to minimize the risk of exposure to L-kynurenine.
Hazard statements for L-kynurenine include “Causes skin irritation” and “May cause respiratory irritation.” These statements highlight the potential harm that can result from exposure to L-kynurenine. It is important to be aware of these hazards when working with the compound to take necessary precautions to protect oneself. By following safety protocols and using appropriate protective equipment, the risks associated with handling L-kynurenine can be mitigated.
Precautionary statements for L-kynurenine include “Wash hands and any exposed skin thoroughly after handling” and “Use only outdoors or in a well-ventilated area.” These statements serve as guidelines for safe handling practices and emphasize the importance of minimizing exposure to L-kynurenine. By following these precautionary measures, individuals can reduce the likelihood of adverse health effects associated with the compound. Proper storage and disposal of L-kynurenine are also important precautions to prevent environmental harm.
