D-Tagatose CAS 87-81-0

1. D-Tagatose CAS 87-81-0 is a low-calorie monosaccharide (1.5 kcal/g) used as a sugar substitute in foods and beverages, providing approximately 92% of the sweetness of sucrose with a lower glycemic response .
2. D-Tagatose serves as a functional prebiotic, promoting the growth of beneficial gut bacteria such as *Lactobacillus* and *Bifidobacterium* while being poorly absorbed in the small intestine .
3. In pharmaceutical research, D-tagatose is used as a stabilizer for therapeutic proteins and peptides, as an excipient in dry powder inhalers, and as a starting material for the synthesis of chiral intermediates .
4. Researchers utilize D-Tagatose in metabolic studies to investigate fructose metabolism, as D-tagatose is converted to fructose in the liver, and to evaluate its potential in managing type 2 diabetes and obesity .

1. D-Tagatose CAS 87-81-0 must be stored in a tightly sealed container in a cool, dry, and well-ventilated environment at room temperature (15-25°C), protected from light and moisture to prevent caking and degradation .
2. D-Tagatose 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 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-Tagatose is released .
2. Collect D-Tagatose 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 the product 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.

1. D-Tagatose CAS 87-81-0 is not classified as highly flammable but may decompose under fire conditions, emitting toxic fumes including carbon monoxide and carbon dioxide .
2. Use D-Tagatose 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-Tagatose 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 .
