3-chloro-2-methylpropylene (CAS 563-47-3), as a highly active halogenated alkene, is a key intermediate in the synthesis of pesticides (phenyclotin, kebovir) and pharmaceuticals. Its strong volatility, flammability, explosiveness and carcinogenicity require strict compliance with safety regulations (explosion-proof equipment, inert gas protection).
Chemical Name: 3-chloro-2-methylpropene (Also known as: methylallyl chloride, 2-methylallyl chloride, isobutylchloride)
Molecular formula: C₄H₇Cl
Molecular weight: 90.55 g/mol
CAS Number: 563-47-3
EINECS No. : 209-251-2
1. Pesticide Synthesis (Core Application
Acaricide intermediate: Chlorinated tert-butylbenzene, a key raw material for the synthesis of styrene-tin.
Insecticide intermediates: Furanol, an intermediate used in the production of Kebawei.
Other pesticides: Participate in the synthesis of herbicides such as methyl fluoxate.
2. Pharmaceuticals and Fine Chemicals
Pharmaceutical intermediates: synthetic reverse transcriptase viral protease inhibitors, muscone, etc.
Polymer additives: Production of sodium methylallyl sulfonate, 3-chloro-2-methylpropylene oxide.
Biomedical research: Reacts with isopropylamine to form N-isopropylmethylacrylamide, which is used as a drug carrier.
3. Other fields
Spice synthesis: Synthesis of high-value spice compounds.
Electronic materials: Participate in the preparation of special materials as organic synthesis reagents.
Health and environmental risks
Toxicity
Oral administration of LD₅₀ = 848 mg/kg in rats (poisoning); It is easily absorbed through the skin, causing burns and respiratory tract irritation.
Carcinogenicity: IARC classifies it as a Group 2B carcinogen (possibly carcinogenic to humans).
Environmental risk: Toxic to aquatic organisms. Leakage into water bodies must be prevented.
Operation and storage requirements
Protective measures
Wear a gas mask, acid and alkali resistant gloves, goggles and anti-static clothing.
Local exhaust ventilation should be provided to avoid contact with oxidants (which may cause combustion).
Storage conditions
Cool and well-ventilated place (≤30℃), protected by inert gas, isolated from oxidants.
Leakage Emergency response
Absorb with sand and soil. Do not rinse with water (it releases heat when exposed to water). When there is a large-scale leakage, the containment is carried out by building embankments and then burned.
