Methyl 4-bromobutyrate CAS 4897-84-1

1. Methyl 4-bromobutyrate CAS 4897-84-1 is primarily used as an alkylating agent and versatile C4-building block in organic synthesis, particularly for introducing the 4-bromobutyryl group into target molecules via nucleophilic substitution or coupling reactions.
2. Methyl 4-bromobutyrate serves as an important intermediate in the synthesis of pharmaceuticals, agrochemicals, and fragrances, including active pharmaceutical ingredients (APIs) and functionalized compounds.
3. Methyl 4-bromobutyrate functions as a monomer or chain extender in polymer chemistry for producing modified polyesters, polyamides, and other specialty materials.

1. Store methyl 4-bromobutyrate CAS 4897-84-1 in a cool, dry, well-ventilated area, protected from light and moisture, in tightly sealed containers made of corrosion-resistant materials.
2. Keep methyl 4-bromobutyrate strictly separate from strong oxidizing agents, strong bases, and reactive metals to prevent hazardous decomposition or violent reactions.
3. Handle methyl 4-bromobutyrate with extreme care using non-sparking tools and grounded equipment; ensure containers are clearly labeled and stored in a dedicated, secure area.

1. Immediately evacuate and isolate the spill area, eliminate all ignition sources, and ensure forced ventilation; avoid direct contact and prevent the liquid from entering drains or soil.
2. Carefully absorb spilled methyl 4-bromobutyrate with inert, non-combustible materials (e.g., sand, vermiculite); collect into sealed, labeled containers for disposal as hazardous chemical waste.
3. Clean the contaminated surface thoroughly with a suitable solvent or detergent under controlled conditions; collect all contaminated materials and dispose of them in full compliance with local, national, and international regulations for corrosive and hazardous substances.

1. Methyl 4-bromobutyrate CAS 4897-84-1 is corrosive and causes severe skin burns, eye damage, and respiratory tract irritation upon contact or inhalation of vapors/mists.
2. Methyl 4-bromobutyrate is harmful if swallowed or inhaled, and repeated or prolonged exposure may cause damage to specific organs.
3. Always handle methyl 4-bromobutyrate in a certified fume hood or with adequate local exhaust, wearing appropriate PPE including chemical-resistant gloves, face shield, chemical goggles, and protective clothing.
