1-Phenyloxindole CAS 3335-98-6

1. 1-Phenyloxindole CAS 3335-98-6 is a heterocyclic building block primarily used as a pharmaceutical intermediate in the synthesis of various bioactive compounds and drug candidates .
2. 1-Phenyloxindole serves as a versatile scaffold in medicinal chemistry for the preparation of indole-based derivatives with potential biological activities .
3. In organic synthesis, 1-phenyloxindole is employed as a key precursor for constructing more complex heterocyclic systems and natural product analogs .
4. Researchers utilize 1-Phenyloxindole as a reference standard in analytical chemistry and as a substrate for studying reactions involving the oxindole core structure .

1. 1-Phenyloxindole must be stored in a tightly sealed container in a cool, dry, and well-ventilated environment, preferably in a cool and dark place below 15°C (room temperature) .
2. 1-Phenyloxindole is stable under recommended storage conditions and should be protected from light and moisture to maintain purity .
3. 1-Phenyloxindole is not classified as a hazardous substance under GHS criteria, but personnel must wear chemical-resistant gloves, safety goggles, and protective clothing when handling this substance .
4. Keep 1-Phenyloxindole away from incompatible materials such as strong oxidizing agents to prevent decomposition; wash thoroughly after handling .

1. Isolate the spill area, ensure adequate ventilation, and wear full personal protective equipment including chemical-resistant gloves and safety goggles when 1-Phenyloxindole is released .
2. Collect 1-Phenyloxindole 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. 1-Phenyloxindole is not classified as highly flammable (NFPA fire rating not specified) but may decompose under fire conditions, emitting toxic fumes .
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 1-Phenyloxindole 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 1-Phenyloxindole 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 .
