Chloroform Extra Pure, or Extra Pure Chloroform, is a high-purity and quality-controlled form of chloroform used for laboratory and chemical applications. It is a halogenated organic compound and an organic solvent that is used in laboratory processes and sample preparation due to its suitable solvating power for many organic compounds.
Chloroform is known by the names Chloroform and Trichloromethane and has the chemical formula CHCl₃. Its molecular weight is 119.37 g/mol. In the Extra Pure grade, in addition to overall purity, specifications such as water content, color, infrared spectrum, and stabilizer content are also controlled.

Chloroform is produced on an industrial scale through chemical processes involving chlorinated compounds. After the production of crude chloroform, separation, distillation, and purification steps are carried out to reduce unwanted compounds.
For the production of the Extra Pure grade, greater control is applied to product quality and impurities such as water and non-volatile residues.
According to the reaction:
CH₄ + 3Cl₂ → CHCl₃ + 3HCl
On a laboratory scale, chloroform can also be prepared through the haloform reaction. However, to achieve the Extra Pure grade, the crude product must undergo additional drying, redistillation, impurity removal, and stabilization steps to obtain the desired quality and purity.
According to the reaction:
CH₃COCH₃ + 3NaOCl → CHCl₃ + CH₃COONa + 2NaOH
Due to its high purity and controlled impurities, Chloroform Extra Pure is used for laboratory and research applications where solvent quality is important:
The main difference between Chloroform Extra Pure and regular chloroform is the level of purity and control of quality specifications and impurities. In the Extra Pure product under consideration, purity and characteristics such as water content, color, residue after evaporation, and stabilizer content are specifically controlled.
Therefore, this grade is more suitable for applications where solvent quality and consistency are important.
Despite its high purity, Chloroform Extra Pure remains a toxic and hazardous substance, and chemical safety requirements must be observed when using it.
According to the safety information for this Extra Pure product, chloroform is harmful if swallowed, toxic if inhaled, and may cause skin irritation and serious eye damage. In addition, the safety classification of this product indicates suspected carcinogenicity, potential harm to the fetus, and the risk of organ damage following prolonged or repeated exposure.
To maintain the quality of Chloroform Extra Pure, the product should be kept in its original, tightly closed container and in a suitable chemical storage area. Unnecessary exposure to its vapors should be avoided, and the product should be stored in a well-ventilated environment.
Chloroform Extra Pure, due to its hazardous classification, must be transported in accordance with the regulations applicable to the transportation of hazardous chemicals. The product container must be intact, tightly closed, and free from leakage, and it must be protected from physical damage and unsuitable environmental conditions during transportation.
When purchasing Chloroform Extra Pure, it is recommended to consider, in addition to the chemical name, the grade, purity, water content, type of stabilizer, brand, product code, and COA. The appropriate product should be selected based on the type of laboratory application and the sensitivity of the process.
