Chloroform is not usually sold in general pharmacies in Bangladesh. Chloroform is a controlled chemical, which can be forbidden or strictly controlled to sell directly to ordinary people due to the risk of abuse.
If you want to buy chloroform for legitimate research, industry or medical work, you can contact authorized chemical suppliers or research lab suppliers. In addition, the authorities concerned of the government of Bangladesh may be allowed before buying.
If you want to be sure that it is found somewhere in your area and how to buy legally, you can contact local pharmacy or chemical suppliers.
