140-57-8 Usage
Description
ARAMITE, a synthetic chlorinated hydrocarbon, is a carcinogenic acaricide with a molecular weight of 334.87 and a density of 1.143 at 20°C. It is characterized by its clear, light-colored oil appearance, with a melting point of 37.3°C and a boiling point of 175°C at 0.1 mm Hg. Technical grade ARAMITE is a dark amber liquid, practically insoluble in water, but miscible in many organic solvents. Initially introduced to the market around 1950, it was used as a pesticide (acaricide) to control mites in plants and animals. However, its manufacture and use were voluntarily discontinued due to its carcinogenic potential, as per a US Environmental Protection Agency (EPA) notice dated 12 April 1977.
Uses
Used in Agricultural Industry:
ARAMITE is used as a miticide for controlling mites, particularly six-spotted mite and European red mite, affecting crops. It was effective against the active mite stage, causing paralysis and disorganized movements of appendages, leading to detachment from the plant. ARAMITE was used in combination with other pesticides to control a wide range of mite species. It was mostly used between 1950 and 1954 in greenhouses in the United States.
It is important to note that ARAMITE's use has been discontinued due to its carcinogenic potential, and there are reports of bans in some European countries. Occupational exposure through dermal contact and inhalation was possible during its use, but its use is no longer recommended due to health and environmental concerns.
Safety Profile
Confirmed carcinogen with experimental carcinogenic, neoplastigenic, and tumorigenic data. Experimental poison by intraperitoneal route. Moderately toxic to humans by ingestion. Moderately toxic experimentally by ingestion. Experimental reproductive effects. A pesticide. When heated to decomposition it emits toxic fumes of Cland SOx. See also ESTERS and SULFUROUS ACID.
Potential Exposure
Aramite is an organochlorine miticide
and antimicrobial agent. Aramite is regulated by EPA
under the Federal Insecticide, Fungicide, and Rodenticide
Act and the Resource Conservation and Recovery Act. The
significant regulatory action was a voluntary cancellation
of the active ingredient registration by the sole producer in
1975.

Toxicity evaluation
Aramite can be released directly into the environment through
its use as an acaricide (miticide); however, this use has been
discontinued. If released to soil, aramite is expected to have no
mobility. Volatilization from moist soil surfaces is not expected
to be an important fate process based on an estimated Henry’s
Law constant of 1.9×10-7 atm m3 mol-1. Biodegradation
data for aramite are not available, and if released into water,
aramite is expected to adsorb to suspended solids and sediments based upon the estimated Koc of 2.0×10+4. Volatilization
from water surfaces is not expected to be an important
fate process based on this compound’s estimated Henry’s Law
constant. Aramite’s potential for bioconcentration in aquatic
organisms is very high. Functional groups of aramite are
susceptible to hydrolysis; however, insufficient data are available
to predict the relative importance or occurrence of chemical
or biological degradation processes in water or soil.
Aramite is hydrolyzed by alkalies and may contribute to
degradation in soil or water. If released into air, aramite is expected
to be physically removed by wet and dry deposition
processes.
Incompatibilities
Incompatible with alkaline material,
such as lime or Bordeaux mixture (slaked lime and copper
sulfate solution).
Waste Disposal
Acid or alkaline hydrolysis
followed by flushing to sewer.
Check Digit Verification of cas no
The CAS Registry Mumber 140-57-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,4 and 0 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 140-57:
(5*1)+(4*4)+(3*0)+(2*5)+(1*7)=38
38 % 10 = 8
So 140-57-8 is a valid CAS Registry Number.
