DL-Dithiothreitol / DTT CAS 3483-12-3

1. DL-Dithiothreitol (DTT) is a reducing agent primarily used in biochemistry to reduce disulfide bonds in proteins, maintaining thiol groups in a reduced state and preventing oxidative cross-linking .
2. DTT CAS 3483-12-3 serves as a protective agent for sulfhydryl groups in enzyme assays, protein purification, electrophoresis, and molecular biology applications where maintaining reducing conditions is critical .
3. DL-Dithiothreitol is employed in research as a chiral resolving agent and in the synthesis of thiol-containing compounds .
4. Researchers utilize this product to study protein folding, enzyme mechanisms, and as a standard reagent for quantifying disulfide bond reduction in biochemical assays .

1. DL-Dithiothreitol must be stored in a tightly sealed container under inert atmosphere (nitrogen or argon) in a cool, dry, and well-ventilated environment at -20°C for long-term stability (up to 3 years) or at 4°C for up to 2 years .
2. DTT CAS 3483-12-3 is classified with GHS hazard statements H302 (Harmful if swallowed), H315 (Causes skin irritation), H319 (Causes serious eye irritation), and H335 (May cause respiratory irritation), with signal word "Warning" .
3. Personnel must wear chemical-resistant gloves, safety goggles with side-shields, and protective clothing when handling this substance, ensuring adequate ventilation in work areas .
4. Keep away from incompatible materials such as strong oxidizing agents to prevent decomposition; for solution storage, prepare aliquots and use within 1 month at -20°C, avoiding repeated freeze-thaw cycles .

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 DL-Dithiothreitol is released .
2. Collect DTT CAS 3483-12-3 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 through licensed chemical destruction or controlled incineration .

1. DL-Dithiothreitol is not classified as highly flammable but may decompose under fire conditions, emitting toxic fumes including carbon monoxide, carbon dioxide, and sulfur oxides .
2. Use water spray, dry chemical powder, carbon dioxide, or alcohol-resistant foam to extinguish fires involving the product; do NOT use a direct water jet as DTT CAS 3483-12-3 may scatter burning material .
3. Firefighters should wear self-contained breathing apparatus in pressure-demand, MSHA/NIOSH approved, and full protective gear when handling burning DL-Dithiothreitol due to hazardous decomposition gases generated by thermal decomposition .
4. During combustion, may emit irritant and toxic fumes; move containers from the fire area if safe to do so, and contain fire runoff to prevent environmental contamination .
