About Chloroform .
Chloroform, or trichloromethane, is an organic compound with formula CHCl3. It is a colorless, sweet-smelling, dense liquid that is produced on a large scale as a precursor to PTFE. It is also a precursor to various refrigerants. It is one of the four chloromethanes and a trihalomethane.
Essential Laboratory and Industrial ReagentChloroform serves as a vital reagent in laboratories and diverse industries, thanks to its purity (minimum 99%) and stability when stored correctly. Its chemical neutrality and relative ease of handling make it suitable for a range of chemical processes, extraction applications, and as a solvent in organic synthesis and analytical work.
Stringent Storage and Handling GuidelinesTo maintain quality and safety, chloroform must be stored in tightly sealed glass or HDPE containers within cool, well-ventilated, and dry environments. This ensures product stability and prevents hazardous vapor accumulation. Adhering to these guidelines reduces exposure risk and maximizes shelf life up to two years.
FAQs of Chloroform .:
Q: How should chloroform be stored to maintain its stability and purity?
A: Chloroform should be kept in a cool, dry, and well-ventilated area, tightly sealed in glass bottles or HDPE containers. This prevents contamination, maintains its purity of at least 99%, and supports a shelf life of up to two years.
Q: What are the recommended applications of chloroform in laboratory and industrial settings?
A: Chloroform is primarily used as a laboratory reagent and in industrial processes for extraction, organic synthesis, and as a solvent, due to its chemical stability and high purity. Its effectiveness extends to analytical chemistry and certain manufacturing workflows.
Q: When is personal protective equipment required while handling chloroform?
A: Personal protective equipment (such as gloves, goggles, and lab coats) is mandatory whenever handling chloroform, since it is toxic if inhaled and can cause skin and eye irritation. Proper ventilation and fume hoods are also recommended during use.
Q: Where can chloroform be procured in India?
A: Chloroform is available throughout India from various distributors, exporters, importers, manufacturers, suppliers, and retailers who adhere to safety and quality standards. It is commonly packaged in glass or HDPE containers and supplied to laboratories and industrial facilities.
Q: What are the main safety hazards and how can they be mitigated during chloroform use?
A: Key hazards include toxicity from inhalation and irritation to the skin and eyes. To minimize risks, use in well-ventilated spaces, avoid inhaling vapors, and wear suitable protective gear. Keep the substance away from ignition sources due to its volatility.
Q: How is the purity and quality of chloroform verified before usage?
A: The purity of chloroform is typically assured by the distributor or manufacturer, verified through assay values (minimum 99%), loss on drying (not more than 0.2%), heavy metals (less than 0.001%), and moisture content (max 0.1%). Certificates of analysis are often provided with each batch.
Q: What benefits does chloroform offer as a solvent or reagent?
A: Chloroform exhibits excellent solvency for a wide range of organic compounds, has a neutral pH, and is easy to separate due to its volatility. This makes it highly valuable in extraction processes, chromatography, and the production of specialty chemicals.
