Aspartame Impurity 4 (Fmoc-D-Phe-OH)(CAS: 86123-10-6)

Aspartame Impurity 4, also known as Fmoc-D-Phe-OH, is a derivative of phenylalanine used primarily in the analysis and purification of aspartame. It has the chemical formula C19H25NO4 and is a white to off-white crystalline solid with high molecular weight. This compound is commonly used in pharmaceutical and research settings for quality control purposes.

Aspartame Impurity 4 (Fmoc-D-Phe-OH) is mainly used in pharmaceutical and analytical research to detect and quantify impurities in aspartame production. It also serves as a building block in the synthesis of other pharmaceutical compounds and is employed in the development of amino acid-based drugs. Its application extends to food science for the study of artificial sweeteners.

Aspartame Impurity 4 (Fmoc-D-Phe-OH) is generally considered safe when handled under standard laboratory conditions. However, as with any chemical, it should be used with appropriate safety measures, such as wearing gloves and goggles. It is not intended for human consumption and should be kept away from children and pets to ensure safety.

Aspartame Impurity 4 (Fmoc-D-Phe-OH) should be stored in a cool, dry, and dark place, ideally at 2-8°C. It is important to maintain low humidity and protect it from light exposure to preserve its stability. The compound should be kept in a sealed container to prevent moisture absorption and contamination.
