Pyridoxal 5-phosphate is the biologically active form of vitamin B6, acting as an essential coenzyme for more than one hundred enzymatic reactions involved in amino acid metabolism, carbohydrate conversion and lipid synthesis in human and animal organisms. It participates in transamination, decarboxylation and racemization of amino acids, regulating protein synthesis and nutrient absorption, and is widely used in pharmaceutical raw materials, nutritional supplements and food fortification industries. It is commonly added to functional food, health products and feed additives to improve animal growth performance, enhance immunity and relieve metabolic disorders. In pharmaceutical field, it is applied in the preparation of drugs for treating neuritis, anemia, dermatitis and vomiting during pregnancy, also used as biochemical reagent for enzyme research, cell culture and microbiological culture medium preparation. Additionally, it serves as an important intermediate in organic synthesis and biochemical analysis standard substance, extensively adopted in life science research, clinical diagnostic reagent development and cosmetic raw material formulation for regulating skin metabolism and maintaining physiological balance.

This compound is low-toxic under normal industrial and laboratory usage conditions, but direct contact still brings certain irritation risk to human body. Skin contact with powder or aqueous solution may cause mild redness, dryness and allergic itching, especially for people with sensitive skin constitution; accidental splashing into eyes will lead to obvious stinging, tearing and conjunctival congestion, requiring immediate flushing with plenty of clean water. Inhalation of fine dust may irritate respiratory mucosa, causing throat dryness, cough and slight chest discomfort. Excessive oral intake in a short time may induce gastrointestinal reactions such as nausea, abdominal distension and diarrhea, and long-term high-dose intake may affect nerve system metabolism. During handling and weighing, operators must wear dust-proof mask, chemical resistant gloves and protective goggles, keep working environment well ventilated and avoid dust floating and aerosol formation. The product should be stored in sealed, dry, cool and dark place, strictly protected from light and high temperature to prevent decomposition and deterioration, kept away from strong oxidants and alkaline substances. Waste materials and residual liquid should be treated according to hazardous biochemical waste regulations, prohibited from arbitrary discharge into domestic sewage and natural water bodies to avoid potential ecological cumulative impact on aquatic organisms.
