4-Chlorobutanoic Acid CAS 627-00-9

1. 4-Chlorobutanoic acid is primarily used as a versatile C4-building block and alkylating agent in organic synthesis, particularly for introducing the 4-chlorobutanoyl group into target molecules.
2. 4-Chlorobutanoic acid CAS 627-00-9 serves as a key intermediate in the synthesis of pharmaceuticals, agrochemicals, and fragrances, including active pharmaceutical ingredients (APIs) and aroma compounds.
3. 4-Chlorobutanoic acid functions as a monomer or chain extender in polymer chemistry for the preparation of functionalized polyesters, polyamides, and other specialty materials.

1. Store 4-chlorobutanoic acid in a cool, dry, well-ventilated area, in tightly sealed containers made of corrosion-resistant materials (e.g., glass or certain plastics) to prevent moisture absorption and degradation.
2. Keep 4-chlorobutanoic acid CAS 627-00-9 separate from strong oxidizing agents, strong bases, and reactive metals to prevent hazardous decomposition or violent reactions.
3. Handle 4-chlorobutanoic acid with care using non-sparking tools and grounded equipment; ensure containers are clearly labeled and stored in a dedicated, secure area.

1. Immediately isolate the spill area, eliminate all ignition sources, and ensure forced ventilation; avoid direct contact and prevent the material from entering drains or soil.
2. Carefully neutralize spilled 4-chlorobutanoic acid CAS 627-00-9 with a suitable alkaline substance (e.g., sodium bicarbonate) if trained to do so safely, then absorb with inert materials (e.g., sand, vermiculite).
3. Collect neutralized residue and contaminated absorbents into sealed, labeled containers for disposal as hazardous chemical waste; clean the surface thoroughly with water and dispose of all waste according to hazardous material regulations.

1. 4-Chlorobutanoic acid is corrosive and causes severe skin burns, eye damage, and respiratory tract irritation upon contact or inhalation of dust/mists.
2. 4-Chlorobutanoic acid CAS 627-00-9 is harmful if swallowed or inhaled, and repeated or prolonged exposure may cause damage to specific organs.
3. Always handle 4-chlorobutanoic acid in a certified fume hood or with adequate local exhaust, wearing appropriate PPE including chemical-resistant gloves, face shield, chemical goggles, and protective clothing.
