D-Galactose CAS 59-23-4

1. D-Galactose is a naturally occurring monosaccharide used as a component in cell culture media for the production of glycoproteins and therapeutic proteins, where D-Galactose CAS 59-23-4 serves as a carbon source and precursor for glycosylation .
2. The compound is employed in metabolic research to study galactose metabolism, galactosemia, and the role of galactose in cellular signaling and energy production .
3. D-Galactose is utilized as a substrate for the synthesis of galactosides, galactooligosaccharides (GOS), and other carbohydrate-based compounds used in food, pharmaceutical, and cosmetic applications .
4. In research models of aging, D-galactose is used to induce aging-related oxidative stress and cognitive decline, enabling the study of anti-aging interventions and neuroprotective mechanisms .

1. D-Galactose 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. D-Galactose CAS 59-23-4 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 D-Galactose CAS 59-23-4 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 D-Galactose is released .
2. Collect D-Galactose CAS 59-23-4 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 D-galactose 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. D-Galactose is not classified as highly flammable but may decompose under fire conditions, emitting toxic fumes including carbon monoxide and carbon dioxide .
2. Use D-Galactose CAS 59-23-4 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 D-Galactose 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 .
