Products Description



D Phenylalanine Powder, is a chemical name, mainly consisting of carbon, hydrogen, oxygen and nitrogen, with the chemical formula C9H11NO2, mainly used as an intermediate in pharmaceuticals. Slightly hazardous to water, do not allow undiluted or large quantities of product to come in contact with groundwater, waterways or sewage systems. Do not discharge material into the surrounding environment without government permission.Phenylalanine, scientific name α-amino-β-phenylpropionic acid, is a kind of α-amino acid. Phenylalanine is a new amino acid first discovered by Schulze and Barbieri in the late 1880s, isolated from lupin seedlings, and proposed an empirical chemical formula as C9H11NO2. Erlemeyer and Lipp first successfully synthesized phenylalanine by chemical synthesis in 1882, but did not explore its spatial configuration in Chemicalbook. Then Fischer accidentally isolated phenylalanine when hydrolyzing casein with hydrochloric acid in 1901. Since then, people's research on phenylalanine has been more in-depth. D-Phenylalanine is a kind of α-amino acid, its physical state is white powder or white crystalline solid at room temperature, its melting point is 283℃, its isoelectric point (25℃) is 5.48, and its solubility in water is 27g/L at 25℃. Slightly soluble in methanol, ethanol, insoluble in ether, etc., specific optical rotation [α]25D=+34.5 (c=1.0, H2O).
