L-Arabinose CAS 5328-37-0

1. L-Arabinose is a naturally occurring pentose sugar primarily used as a low-calorie sweetener and prebiotic in functional foods and beverages, where it inhibits sucrase activity and reduces postprandial blood glucose levels .
2. L-Arabinose CAS 5328-37-0 serves as a key building block in organic synthesis for the preparation of L-ribose, L-nucleosides, and other chiral intermediates used in antiviral and anticancer drug development .
3. L-Arabinose is employed as a carbon source in microbial fermentation and as a substrate for studying pentose metabolism, enzyme kinetics, and the production of biofuels and biochemicals .
4. Researchers utilize L-Arabinose CAS 5328-37-0 as a reference standard in carbohydrate analysis and as a component in cell culture media to study glycosylation and metabolic pathways .

1. L-Arabinose must be stored in a tightly sealed container in a cool, dry, and well-ventilated environment at room temperature, protected from light and moisture .
2. L-Arabinose CAS 5328-37-0 is classified as non-hazardous under normal handling conditions according to GHS criteria, but may cause mild skin, eye, and respiratory tract irritation .
3. Personnel should wear chemical-resistant gloves, safety goggles with side-shields, and protective clothing when handling this substance, avoiding formation of dust and aerosols .
4. Keep L-Arabinose CAS 5328-37-0 away from incompatible materials such as strong oxidizing agents; the compound is hygroscopic and should be stored in a tightly sealed container to prevent moisture absorption .

1. Isolate the spill area, ensure adequate ventilation, and wear full personal protective equipment including chemical-resistant gloves, safety goggles, and suitable dust respirator when L-Arabinose is released .
2. Collect L-Arabinose CAS 5328-37-0 by sweeping or vacuuming without creating dust using non-sparking tools, and place into suitable closed containers for disposal .
3. Avoid creating dust clouds during cleanup to prevent respiratory exposure; prevent L-arabinose 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 (DOT, IATA, IMDG) .

1. L-Arabinose is not classified as highly flammable but may decompose under fire conditions, emitting toxic fumes including carbon monoxide and carbon dioxide .
2. Use L-Arabinose CAS 5328-37-0 water spray, dry chemical powder, carbon dioxide, or alcohol-resistant foam to extinguish fires involving the product .
3. Firefighters should wear self-contained breathing apparatus in pressure-demand, MSHA/NIOSH approved, and full protective gear when handling burning L-Arabinose 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 .
