Trichloromethane CAS:67-66-3

Trichloromethane CAS:67-66-3, commonly known as chloroform, with CAS number 67-66-3, is an important halogenated hydrocarbon organic chemical raw material with the chemical formula CHCl₃. Its molecular structure contains three chlorine atoms and one hydrogen atom, possessing core advantages such as high solubility, low boiling point, and excellent extraction and separation properties. It is a commonly used solvent, extractant, and reaction medium in industrial production. However, trichloromethane has certain anesthetic and toxic properties and a potential impact on the environment. Its production, use, and emissions must strictly adhere to relevant safety and environmental standards. Currently, it is widely used in various fields such as medicine, chemicals, electronics, and food, and is an indispensable basic chemical product in the industrial chain.

Chloroform, with its core advantages of high solubility, low boiling point, and excellent extraction and separation properties, is widely used in various industrial fields such as pharmaceuticals, chemicals, electronics, and food. It is an important basic chemical raw material and functional additive; however, due to its certain toxicity and environmental impact, its application requires strict adherence to relevant safety regulations, and some traditional application scenarios are gradually being replaced by environmentally friendly alternative products.

1. Pharmaceutical Field: Pharmaceutical Synthesis Intermediates and Extractants (Core Application Area)

Chloroform is one of the indispensable raw materials in the pharmaceutical industry, mainly used in the synthesis of antibiotics, vitamins, and hormones, as well as in the extraction and separation of active ingredients from natural medicines. Its high purity and low impurity characteristics ensure the safety and efficacy of drug synthesis.

2. Chemical Industry: Solvents and Organic Synthesis Raw Materials

Chloroform is a commonly used "universal solvent" in the chemical industry and an important raw material for the synthesis of other halogenated hydrocarbons, dyes, fragrances, rubber additives, and other products, suitable for a variety of organic synthesis reactions.

3. Electronics Industry: Precision Cleaning Agents and Etchants

The high solubility and low residue characteristics of trichloromethane make it suitable for precision cleaning and etching processes in the electronics industry, ensuring the cleanliness and processing accuracy of electronic components.

4. Food Sector: Food Additive Extractant (Strictly Limited Use)

As a food processing aid permitted by the state (GB 2760-2014), chloroform can be used for the extraction and separation of food additives (such as flavors, fragrances, and natural pigments). However, due to its toxicity, its usage and residual levels must be strictly controlled.

5. Other Fields

- Analytical and Testing Field: Used as a solvent or extractant in gas chromatography (GC) and high-performance liquid chromatography (HPLC) analysis for sample pretreatment, helping to separate and detect target components in samples;

- Refrigeration Field (Traditional application, currently limited): Historically used in the synthesis of Freon refrigerants (such as R22), but due to Freon's ozone-depleting properties, its production and use are now restricted globally, and this application is gradually declining;

- Scientific Research Field: Widely used as a common solvent and reaction medium in laboratory research experiments in fields such as organic chemistry, biochemistry, and environmental science.
