2'-fucosyllactose CAS 41263-94-9

1. 2'-Fucosyllactose is the most abundant human milk oligosaccharide (HMO), constituting over 30% of total HMOs, and is primarily used as a prebiotic ingredient in infant formula, dietary supplements, and medical foods to support the development of a healthy gut microbiota .
2. 2'-fucosyllactose CAS 41263-94-9 serves as a soluble prebiotic fiber that is resistant to digestion, selectively promotes the growth of beneficial *Bifidobacterium* species, and significantly enhances the adhesion of these bacteria to the intestinal mucosa .
3. 2'-Fucosyllactose functions as a soluble receptor decoy, structurally mimicking gut epithelial glycans to prevent the adhesion of pathogenic bacteria to the intestinal lining, thereby reducing the risk of infections .
4. Research indicates that 2'-Fucosyllactose has immunomodulatory effects and can influence brain development via the gut-brain axis; studies in animal models have demonstrated that oral intake can enhance learning, memory, and long-term potentiation (LTP) in the hippocampus .

1. 2'-Fucosyllactose is hygroscopic and must be stored in a tightly sealed container in a cool, dry, and well-ventilated environment, protected from light and moisture to prevent degradation .
2. For long-term stability, it is recommended to store 2'-fucosyllactose powder at -20°C (stable for up to 3 years) or at 4°C for shorter periods; solutions should be prepared in aliquots and stored at -20°C for up to 1 month, avoiding repeated freeze-thaw cycles .
3. 2'-Fucosyllactose is generally recognized as safe (GRAS) by the FDA and approved as a novel food by EFSA; however, personnel handling the pure compound should wear chemical-resistant gloves, safety goggles, and protective clothing to avoid mild skin, eye, and respiratory irritation .
4. Keep 2'-fucosyllactose away from incompatible materials such as strong oxidizing agents to prevent decomposition, and store containers upright to avoid moisture ingress .

1. Isolate the spill area, ensure adequate ventilation, and wear full personal protective equipment including chemical-resistant gloves, safety goggles, and a suitable dust respirator when 2'-Fucosyllactose is released .
2. Collect 2'-fucosyllactose by sweeping or vacuuming without creating dust using non-sparking tools, and place it into suitable closed containers for disposal .
3. Avoid creating dust clouds during cleanup to prevent respiratory exposure; prevent 2'-Fucosyllactose from entering drains or water courses .
4. Dispose of collected material according to local, state, and federal environmental regulations; the substance is considered non-hazardous for transport under normal conditions .

1. 2'-Fucosyllactose is not classified as highly flammable but is a combustible solid that may decompose under fire conditions, emitting toxic fumes including carbon monoxide and carbon dioxide .
2. Use water spray, dry chemical powder, carbon dioxide, or alcohol-resistant foam to extinguish fires involving 2'-Fucosyllactose; do NOT use a direct water jet as 2'-fucosyllactose may scatter burning material .
3. Firefighters should wear self-contained breathing apparatus in pressure-demand, MSHA/NIOSH approved, and full protective gear when handling burning 2'-Fucosyllactose due to hazardous decomposition gases generated by thermal decomposition .
4. During combustion, may emit irritant and toxic fumes; contain fire runoff to prevent environmental contamination .
