Application
1. Boc-Cys(Acm)-OH is primarily used as a protected, orthogonally bifunctional cysteine derivative in solid-phase peptide synthesis (SPPS) to introduce cysteine residues with a thiol-protecting Acm group .
2. Boc-Cys(Acm)-OH CAS 19746-37-3 enables selective disulfide bond formation in peptide synthesis, as the Acm group remains stable during Boc chemistry and can be removed selectively with iodine or mercuric acetate .
3. Boc-Cys(Acm)-OH serves as a valuable tool for investigating protein structure and function, including protein labeling, modification studies, and protein-ligand interaction analysis .
4. Researchers utilize this product as a reversible inhibitor of cysteine proteases such as cathepsin B and calpain, binding to their active sites to study enzyme mechanisms .
Storage and Precautions
1. Boc-Cys(Acm)-OH must be stored in a tightly sealed container in a cool, dry, and well-ventilated environment at 2-8°C, with long-term storage recommended at -20°C .
2. Boc-Cys(Acm)-OH CAS 19746-37-3 should be protected from light, moisture, and incompatible materials such as strong oxidizing agents to maintain stability .
3. Personnel must wear chemical-resistant gloves, safety goggles, and protective clothing when handling Boc-Cys(Acm)-OH, avoiding dust formation and ensuring adequate ventilation .
4. Avoid inhalation of dust particles and prevent contact with skin, eyes, and clothing, using personal protective equipment and washing thoroughly after handling .
Emergency response to leakage
1. Isolate the spill area, ensure adequate ventilation, and avoid dust formation when Boc-Cys(Acm)-OH is released, using personal protective equipment and removing ignition sources .
2. Collect Boc-Cys(Acm)-OH CAS 19746-37-3 by sweeping or shoveling without creating dust and place into suitable closed containers for disposal, using spark-proof tools if necessary .
3. Avoid creating dust clouds when cleaning up Boc-Cys(Acm)-OH powder to prevent respiratory exposure and airborne contamination .
4. Prevent the product from entering drains or water courses, and dispose of collected material according to local environmental regulations .
Fire prevention measures
1. Boc-Cys(Acm)-OH is not classified as highly flammable but may decompose under high heat conditions, with a flash point of 105°C and decomposition temperature of 220°C .
2. Use dry chemical powder, carbon dioxide, or alcohol-resistant foam to extinguish fires involving the product .
3. Firefighters Boc-Cys(Acm)-OH CAS 19746-37-3 should wear self-contained breathing apparatus and full protective gear when handling burning Boc-Cys(Acm)-OH due to hazardous decomposition gases .
4. Hazardous decomposition products formed under fire conditions include carbon oxides, nitrogen oxides (NOx), and sulfur oxides .
