Application
1. Fmoc-Thr(tBu)-OH is primarily used as a protected amino acid building block in solid-phase peptide synthesis (SPPS) for introducing threonine residues into peptides and proteins .
2. Fmoc-Thr(tBu)-OH CAS 71989-35-0 features dual protection with an Fmoc group on the alpha-amino group and a tert-butyl (tBu) group on the side chain hydroxyl, which prevents side reactions during peptide chain elongation .
3. Fmoc-Thr(tBu)-OH is employed in pharmaceutical research for developing enzyme inhibitors, peptide-based therapeutics, and bioactive molecules requiring protected threonine .
4. Researchers utilize this product in Fmoc SPPS strategies, where the tBu group is cleaved simultaneously with TFA during final deprotection .
Storage and Precautions
1. Fmoc-Thr(tBu)-OH must be stored in a tightly sealed container in a cool, dry, and well-ventilated environment at 2-8°C .
2. Fmoc-Thr(tBu)-OH CAS 71989-35-0 should be protected from light, moisture, and incompatible materials such as strong oxidizing agents and strong acids/bases .
3. Personnel must wear chemical-resistant gloves, safety goggles, and protective clothing when handling Fmoc-Thr(tBu)-OH .
4. Avoid inhalation of dust particles and prevent contact with skin, eyes, and clothing when working with this substance .
Emergency response to leakage
1. Isolate the spill area and ventilate the space immediately when Fmoc-Thr(tBu)-OH is released .
2. Collect Fmoc-Thr(tBu)-OH CAS 71989-35-0 using clean tools and place into a suitable container for disposal or recovery .
3. Avoid creating dust clouds when sweeping up Fmoc-Thr(tBu)-OH powder to minimize airborne contamination .
4. Clean the affected area thoroughly with water after removing all visible traces of the compound .
Fire prevention measures
1. Fmoc-Thr(tBu)-OH is not classified as highly flammable but may decompose under high heat conditions .
2. Use dry chemical powder, carbon dioxide, or water spray to extinguish fires involving the product .
3. Firefighters Fmoc-Thr(tBu)-OH CAS 71989-35-0 should wear self-contained breathing apparatus when handling burning Fmoc-Thr(tBu)-OH due to hazardous decomposition gases .
4. Hazardous decomposition products formed under fire conditions include carbon oxides and nitrogen oxides (NOx) .
