FAQ

What are the physical and chemical properties of L-tyrosine (CAS: 7423-92-9)?

L-tyrosine is a white crystalline powder with a molecular weight of 181.19 g/mol. It is slightly soluble in water and readily soluble in aqueous solutions. Chemically, it is moderately reactive and can undergo hydrolysis and condensation reactions. L-tyrosine is stable under normal storage conditions but should be protected from moisture and light.

How is L-tyrosine (CAS: 7423-92-9) typically synthesized?

L-tyrosine is synthesized through the reductive amination of 4-hydroxybenzaldehyde with ammonia in the presence of a catalyst like palladium on carbon. The process is highly selective and yields up to 90% L-tyrosine. Other methods include microbiological fermentation and chemical synthesis from L-phenylalanine.

What industries use L-tyrosine (CAS: 7423-92-9)?

L-tyrosine is widely used in the pharmaceutical industry for producing drugs, in the food industry as an additive, in the cosmetic industry for skin care products, and in the agricultural industry as an amino acid supplement. It is also used in the production of polymers and as a precursor in the synthesis of other chemicals and materials.

What precautions should be taken when handling L-tyrosine (CAS: 7423-92-9)?

When handling L-tyrosine, wear appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Store it in a cool, dry place away from moisture and light. Use a fume hood during synthesis to avoid inhalation of aerosols. In case of a spill, immediately clean up with caution and refer to the safety data sheet (SDS) for detailed instructions.
