D-Xylose CAS 58-86-6

1. D-Xylose CAS 58-86-6 is a pentose sugar used in diagnostic tests to assess intestinal absorption function, where urinary excretion levels after oral administration help differentiate between malabsorption and other gastrointestinal disorders .
2. D-Xylose serves as a precursor for the industrial production of xylitol via catalytic hydrogenation, and is used as a sweetener in low-calorie and diabetic-friendly food products .
3. D-Xylose is utilized in research as a carbon source for microbial fermentation, particularly for the production of biofuels, and in the study of pentose metabolism in bacteria and yeast .
4. In biochemical research, D-Xylose is used as a reference standard in carbohydrate analysis, as a building block in the synthesis of xylosides and glycoconjugates, and in cell culture media formulations .

1. D-Xylose CAS 58-86-6 must be stored in a tightly sealed container in a cool, dry, and well-ventilated environment at room temperature, protected from light and moisture to prevent caking and microbial growth .
2. D-Xylose 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-Xylose 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-Xylose CAS 58-86-6 is released .
2. Collect D-Xylose 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-Xylose CAS 58-86-6 is not classified as highly flammable but may decompose under fire conditions, emitting toxic fumes including carbon monoxide and carbon dioxide .
2. Use D-Xylose 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-Xylose 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 .
