2,7-Dibromo-9,9-difluoro-9H-fluorene is a chemical compound that is commonly used in the production of various downstream products.
It is an important intermediate in the manufacture of a range of chemicals, including refrigerants, plastics, and pharmaceuticals.
Upstream Products
The production of 2,7-dibromo-9,9-difluoro-9H-fluorene typically involves several upstream processes.
The precursor to this compound is 2,7-dibromo-9H-fluorene, which is synthesized from 9,9-bis(trifluoromethyl)fluorene.
This intermediate is then treated with a reagent such as hydrogen chloride to introduce the two bromine atoms.
Downstream Products
The primary downstream products of 2,7-dibromo-9,9-difluoro-9H-fluorene are refrigerants, plastics, and pharmaceuticals.
The compound is used as an intermediate in the production of refrigerants, which are used in air conditioning and refrigeration systems.
It is also used in the production of fluoropolymers, which are a class of plastics that are commonly used in applications that require high temperature resistance, chemical resistance, and non-stick properties.
Finally, 2,7-dibromo-9,9-difluoro-9H-fluorene is used in the production of certain pharmaceuticals, including some anesthetics and anti-inflammatory drugs.
Refrigerants
One of the primary downstream products of 2,7-dibromo-9,9-difluoro-9H-fluorene is the refrigerant R-22 (dichlorodifluoromethane).
R-22 is commonly used in air conditioning and refrigeration systems, particularly in household appliances such as refrigerators and air conditioners.
It is also used in commercial and industrial applications, such as in refrigerated trucks and walk-in coolers.
Fluoropolymers
Another important downstream product of 2,7-dibromo-9,9-difluoro-9H-fluorene is fluoropolymers.
These plastics are used in a wide range of applications that require high temperature resistance, chemical resistance, and non-stick properties.
Some examples of fluoropolymers include Teflon, which is used in non-stick cookware, and Gore-Tex, which is used in outdoor clothing and equipment.
Pharmaceuticals
2,7-dibromo-9,9-difluoro-9H-fluorene is used in the production of certain pharmaceuticals, including some anesthetics and anti-inflammatory drugs.
One example of a pharmaceutical that contains 2,7-dibromo-9,9-difluoro-9H-fluorene as an intermediate is the anesthetic drug Enflurane (2,7-dibromo-1,3-dichloro-5,6-defluoro-10H-pyrrole-1,2-epoxide).
Enflurane is used in inhalational anesthesia and has a short duration of action, making it useful for short procedures.
Conclusion
2,7-dibromo-9,9-difluoro-9H-fluorene is an important intermediate in the production of several downstream products, including refrigerants, fluoropolymers, and pharmaceuticals.
Its use in these various applications highlights the versatility of this compound and the important role it plays in the chemical industry
