Phthalide CAS 87-41-2

1. Phthalide is a heterocyclic lactone primarily used as a key intermediate in the synthesis of pharmaceuticals, agrochemicals, and fine chemicals .
2. Phthalide CAS 87-41-2 serves as a building block for the preparation of dyes, fragrances, and functional materials, where its lactone ring enables versatile chemical transformations .
3. Phthalide is employed in organic synthesis as a precursor for the production of o-xylene derivatives and other aromatic compounds .
4. Researchers utilize Phthalide CAS 87-41-2 as a reference standard in analytical chemistry and as a starting material for the synthesis of bioactive molecules with potential therapeutic applications .

1. Phthalide must be stored in a tightly sealed container in a cool, dry, and well-ventilated environment, protected from light and moisture; recommended storage at room temperature in a cool, dark place .
2. Phthalide CAS 87-41-2 is classified with GHS hazard statements 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, strong acids, and strong bases 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, safety goggles, and suitable dust respirator when Phthalide is released .
2. Collect Phthalide CAS 87-41-2 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. Phthalide is not classified as highly flammable but may decompose under fire conditions, emitting toxic fumes including carbon monoxide and carbon dioxide .
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 Phthalide CAS 87-41-2 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 Phthalide 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 .
