Chloroform is found in spearmint. Indirect food additive arising from adhesives and polymers Chloroform is a common solvent in the laboratory because it is relatively unreactive, miscible with most organic liquids, and conveniently volatile. Chloroform is used as a solvent in the pharmaceutical industry and for producing dyes and pesticides. Chloroform is an effective solvent for alkaloids in their base form and thus plant material is commonly extracted with chloroform for pharmaceutical processing. For example, it is commercially used to extract morphine from poppies and scopolamine from Datura plants. Chloroform containing deuterium (heavy hydrogen), CDCl3, is a common solvent used in NMR spectroscopy. It can be used to bond pieces of acrylic glass (also known under the trade names Perspex and Plexiglas). Chloroform is a solvent of phenol:chloroform:isoamyl alcohol 25:24:1 is used to dissolve non-nucleic acid biomolecules in DNA and RNA extractions. Chloroform is the organic compound with formula CHCl3. It does not undergo combustion in air, although it will burn when mixed with more flammable substances. It is a member of a group of compounds known as trihalomethanes. Chloroform has myriad uses as a reagent and a solvent. It is also considered an environmental hazard. Several million tons are produced annually. The output of this process is a mixture of the four chloromethanes: chloromethane, dichloromethane, chloroform (trichloromethane), and carbon tetrachloride, which are then separated by distillation. The total global flux of chloroform through the environment is approximately 660000 tonnes per year, and about 90% of emissions are natural in origin. Many kinds of seaweed produce chloroform, and fungi are believed to produce chloroform in soil. Abiotic process is also believed to contribute to natural chloroform productions in soils although the mechanism is still unclear. Chloroform volatilizes readily from soil and surface water and undergoes degradation in air to produce phosgene, dichloromethane, formyl chloride, carbon monoxide, carbon dioxide, and hydrogen chloride. Its half-life in air ranges from 55 to 620 days. Biodegradation in water and soil is slow. Chloroform does not significantly bioaccumulate in aquatic organisms.

Thionyl chloride appears as a colorless to yellow fuming liquid with a suffocating pungent odor. Boiling point 79 °C. A lachrymator. Highly corrosive and toxic. Long-term inhalation of low concentrations or short-term inhalation of high concentrations has adverse health effects. Thionyl chloride is a sulfinyl halide in which both of the halide atoms are chorines. It is a sulfinyl halide and a chlorine molecular entity.

Nickel Carbonate is a light green, crystalline inorganic compound that produces toxic gases upon heating. Nickel carbonate is used in electroplating, to prepare nickel monoxide, to make colored glass and as a catalyst in the treatment of wastewater. Exposure to this substance can cause severe dermatitis, skin and asthma-like allergies and affects the lungs, kidneys, gastrointestinal tract and neurological system. Nickel carbonate is a known carcinogen and is associated with an increased risk of developing lung and nasal cancers. (NCI05) Nickel Carbonate can cause cancer according to California Labor Code. Nickel carbonate is a chemical compound of nickel. Nickel is a chemical compound with the atomic number 28. It is found abundantly in nature in laterite ore minerals, such as limonite, garnierite, and pentlandite. Nickel has a biological role and is found in certain enzymes, including urease, hydrogenase, methylcoenzyme M reductase, and carbon monoxide dehydrogenase. (L40, L41)

Deuterated chloroform is a deuterated compound that is an isotopologue of chloroform in which the hydrogen atom is replaced with deuterium. Commonly used as a solvent in proton NMR spectroscopy. It has a role as a non-polar solvent, a NMR solvent and a NMR chemical shift reference compound. It is a deuterated compound and a member of chloromethanes.
