Description
Chlorendic acid, also known as Hexachlorobicyclo[2.2.1]hept-5-ene-2,3-dicarboxylic acid, is a fine white free-flowing crystalline solid or white powder with no odor. It is a bridged organochlorine compound resulting from the Diels-Alder reaction of hexachlorocyclopentadiene with maleic anhydride, followed by hydrolysis of the resulting anhydride. Chlorendic acid is used as a chemical intermediate in the preparation of fire-retardant polyester resins and plasticizers.
Uses
1. Used in Flame Retardant Applications:
Chlorendic acid is used as a flame retardant in various materials, including polyurethane foams, resins, plasticizers, coatings, epoxy resins, and wool fabrics. It helps to slow down the spread of fire and improve the fire resistance of these materials.
2. Used in Manufacturing Alkyl Resins:
Chlorendic acid is utilized in the production of alkyl resins, which are specifically designed for use in special paints and inks. These resins provide enhanced properties such as durability, resistance to chemicals, and improved adhesion.
3. Used in Manufacturing Polyester Resins:
Chlorendic acid is employed in the manufacture of polyester resins with special applications in electrical systems, paneling, engineering plastics, and paint. These resins offer improved mechanical, thermal, and electrical properties, making them suitable for a wide range of applications.
4. Used in Corrosion-Resistant Applications:
Chlorendic acid is used in the production of corrosion-resistant tanks, piping, and scrubbers. These materials are essential in various industries, such as chemical processing, water treatment, and the oil and gas sector, where corrosion resistance is crucial for the longevity and safety of equipment.
5. Used as an Extreme-Pressure Lubricant:
Chlorendic acid is also utilized as an extreme-pressure lubricant, providing enhanced lubrication under high-pressure and high-temperature conditions. This application is particularly useful in the automotive, aerospace, and industrial sectors, where components are subjected to extreme operating conditions.
6. Environmental and Toxicological Considerations:
It is important to note that Chlorendic acid has been identified as a toxic and environmental pollutant, being listed on the US EPA Toxic Release Inventory (TRI). As a result, its use and disposal must be carefully managed to minimize its impact on the environment and human health.
Air & Water Reactions

Shipping
UN2928 Toxic solids, corrosive, organic, n.o.s.,
Hazard Class: 6.1; Labels: 6.1-Poisonous materials,
8-Corrosive material, Technical Name Required.
Incompatibilities
Compounds of the carboxyl group react
with all bases, both inorganic and organic (i.e., amines)
releasing substantial heat, water, and a salt that may be
harmful. Incompatible with arsenic compounds (releases
hydrogen cyanide gas), diazo compounds, dithiocarbamates, isocyanates, mercaptans, nitrides, sulfides (releasing
heat, toxic, and possibly flammable gases), thiosulfates,
and dithionites (releasing hydrogen sulfate and oxides of
sulfur).
Waste Disposal
Dispose of contents and container to an approved waste disposal plant. All federal, state,
and local environmental regulations must be observed.
Check Digit Verification of cas no
The CAS Registry Mumber 115-28-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,1 and 5 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 115-28:
(5*1)+(4*1)+(3*5)+(2*2)+(1*8)=36
36 % 10 = 6
So 115-28-6 is a valid CAS Registry Number.
