Bromodichloromethane is a trihalomethane with formula C H Br Cl 2.It is a colorless, nonflammable liquid which will dissolve in water, or evaporate in air. [1] Most of the chemical is produced through the chlorine disinfection process, [1] and as a result it can occur in municipally-treated drinking water. [2]
Dibromochloromethane was formerly used as a flame retardant and as an intermediate in chemicals manufacturing. Today it is used only as a laboratory reagent.
Dibromomethane is prepared commercially from dichloromethane via bromochloromethane: . 6 CH 2 Cl 2 + 3 Br 2 + 2 Al → 6 CH 2 BrCl + 2 AlCl 3 CH 2 Cl 2 + HBr → CH 2 BrCl + HCl. The latter route requires aluminium trichloride as a catalyst. [3]
Bromochloromethane or methylene bromochloride and Halon 1011 is a mixed halomethane.It is a heavy low-viscosity liquid with refractive index 1.4808.. Halon 1011 was invented for use in fire extinguishers in Germany during the mid-1940s, in an attempt to create a less toxic, more effective alternative to carbon tetrachloride.
Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...
In people with pre-existing heart problems, exposure to DCM can cause abnormal heart rhythms and/or heart attacks, sometimes without any other symptoms of overexposure. [28] People with existing liver , nervous system , or skin problems may worsen after exposure to methylene chloride.
3,3′,5,5′-Tetramethylbenzidine or TMB is a chromogenic substrate used in staining procedures in immunohistochemistry as well as being a visualising reagent used in enzyme-linked immunosorbent assays (). [1]
3,3'-Dichlorobenzidine is an organic compound with the formula (C 6 H 3 Cl(NH 2)) 2.The pure compound is pale yellow, but commercial samples are often colored. It is barely soluble in water and is often supplied as a wet paste.
