FAQ

What is Phenylalanine (CAS: 673-06-3)?

Phenylalanine is an essential amino acid with the chemical formula C9H11NO2. It is a building block for proteins and plays a key role in the production of neurotransmitters like dopamine and norepinephrine. Phenylalanine is also used in the synthesis of tyrosine, another important amino acid. It is commonly found in foods such as meat, dairy, and eggs, and is available as a dietary supplement.

What are the main uses of Phenylalanine (CAS: 673-06-3)?

Phenylalanine is widely used in pharmaceuticals as a precursor for drugs like amphetamines and aspartame. In the food industry, it serves as a flavor enhancer and is a component of artificial sweeteners. It is also used in research for studying protein structure and in the production of various chemical compounds. Additionally, it is a critical nutrient for individuals with certain dietary restrictions or medical conditions.

Is Phenylalanine (CAS: 673-06-3) safe?

Phenylalanine is generally safe when consumed in normal dietary amounts. However, individuals with phenylketonuria (PKU) must avoid it as it can cause serious health issues. Proper handling and storage are necessary to prevent contamination. Safety guidelines recommend using protective equipment when handling large quantities or in industrial settings to minimize exposure risks.

How should Phenylalanine (CAS: 673-06-3) be stored?
