L-Ribose CAS 24259-59-4

1. L-Ribose is a non-naturally occurring pentose sugar used as a key building block in the synthesis of L-nucleoside analogs, which are important in the development of antiviral and anticancer therapeutics .
2. L-Ribose CAS 24259-59-4 serves as a chiral precursor in organic synthesis for the preparation of L-ribonucleosides and L-ribonucleotides, which exhibit enhanced metabolic stability compared to their D-counterparts .
3. L-Ribose is employed in biochemical research to study the stereospecificity of enzymes involved in carbohydrate metabolism and nucleoside biosynthesis .
4. Researchers utilize L-ribose as a reference standard in analytical chemistry for carbohydrate analysis and as a starting material for the synthesis of modified nucleotides and oligonucleotides .

1. L-Ribose 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-Ribose CAS 24259-59-4 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 L-Ribose CAS 24259-59-4 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 L-Ribose is released .
2. Collect L-Ribose CAS 24259-59-4 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 L-ribose 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-Ribose is not classified as highly flammable but may decompose under fire conditions, emitting toxic fumes including carbon monoxide and carbon dioxide .
2. Use L-Ribose CAS 24259-59-4 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 L-Ribose 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 .
