51-83-2 Usage
Chemical Properties
Different sources of media describe the Chemical Properties of 51-83-2 differently. You can refer to the following data:
1. white crystalline powder
2. Carbachol chloride is a crystalline odorless
powder which, on standing in an open container, develops
a faint odor resembling that of an aliphatic amine.
Originator
Miostat,Alcon,US,1979
Uses
Different sources of media describe the Uses of 51-83-2 differently. You can refer to the following data:
1. Carbachol is a cholinergic agonist and is used for the treatment of glaucoma. It is also used as ophthalmic solution (eye drops) during ophthalmic surgery.
2. Carbamylcholine Chloride is a cholinergic receptor agonist. Studies show that Carbamylcholine Chloride is resistant to the action of cholinesterases. Carbamylcholine Chloride also displays antiapoptotic effects in cerebellar granule neurons.
3. cholinergic, miotic
Definition
An acetylcholine counterfit molecule that is not
inactivated by acetylcholinesterase and is a slowly
hydrolyzed cholinergic agonist that acts at both
muscarinic and nicotinic receptors.
Manufacturing Process
About 14 g of choline chloride are stirred with a solution of about 20 g of
phosgene in 100 g of chloroform for about two hours at room temperature.
The mixture becomes a two-phase liquid mixture. Hydrochloric acid and
excess phosgene are removed by distillation in vacuo. Chloroform is added to
the syrup, and the mixture is then added to a solution of excess ammonia in
chloroform which was cooled with solid carbon dioxide-acetone. The mixture is
filtered, and the solid is extracted with hot absolute alcohol. The solid in the
alcoholic solution is precipitated with ether, and filtered. It is recrystallized
from a methyl alcohol-ether mixture; the carbaminoyl-choline chloride
obtained has a melting point of about 208°-210°C.

Therapeutic Function
Cholinergic
General Description
Different sources of media describe the General Description of 51-83-2 differently. You can refer to the following data:
1. Prismatic crystals or powder. Odorless, but develops a faint odor of aliphatic amine upon standing in an open container. Cholinergic, parasympathomimetic, used chiefly in large animals, especially for colic in the horse.
2. Carbachol forms a carbamylester in the active site of AChE, which is hydrolyzedmore slowly than an acetyl ester. This slower hydrolysis ratereduces the amount of free enzyme and prolongs the durationof ACh in the synapse. Carbachol also stimulates theautonomic ganglia and causes contraction of skeletal musclebut differs from a true muscarinic agent in that it does nothave cardiovascular activity despite the fact that it seems toaffect M2 receptors.
Air & Water Reactions
Hygroscopic.
Reactivity Profile
Carbachol is a carbamate ester. Carbamates are chemically similar to, but more reactive than amides. Like amides they form polymers such as polyurethane resins. Carbamates are incompatible with strong acids and bases, and especially incompatible with strong reducing agents such as hydrides. Flammable gaseous hydrogen is produced by the combination of active metals or nitrides with carbamates. Strongly oxidizing acids, peroxides, and hydroperoxides are incompatible with carbamates.
Hazard
Deadly poison; may cause lowered blood
pressure, venous dilation, nausea or vomiting,
sweating and lachrymation; a parasympathetic
nerve stimulant.
Health Hazard
Highly toxic by mouth.
Fire Hazard
When heated to decomposition, Carbachol emits very toxic fumes of chloride and nitrogen oxides. The aqueous solution is stable even when heated.
Biological Activity
Cholinergic receptor agonist that is resistant to the action of cholinesterases. Blocks apoptosis in cerebellar granule neurons.
Biochem/physiol Actions
Non-selective cholinergic agonist that is resistant to the action of cholinesterases; inhibits apoptotic death of cultured neurons, and may induce apoptosis in thymocytes.
Clinical Use
Carbachol is a miotic and has been used to reduce the intraoculartension of glaucoma when a response cannot beobtained with pilocarpine or neostigmine. Penetration of thecornea is poor but can be enhanced by the use of a wettingagent in the ophthalmic solution. In addition to its topicaluse for glaucoma, carbachol is used during ocular surgery,when a more prolonged miosis is required than can be obtainedwith ACh chloride.
Potential Exposure
Used in veterinary medicine as a
cholinergic; parasympathomimetic, used chiefly in large
animals, especially for colic in the horse
Incompatibilities
Carbachol chloride is a carbamate ester.
Esters are generally incompatible with nitrates. Moisture
may cause hydrolysis or other forms of decomposition.
Carbamates are incompatible with strong acids and bases,
and especially incompatible with strong reducing agents
such as hydrideds and active metals. Contact with active
metals or nitrides form flammable gaseous hydrogen.
Incompatible with strongly oxidizing acids, peroxides, and
hydroperoxides.
Waste Disposal
It is inappropriate and possibly dangerous to the environment to dispose of expired or
waste pharmaceuticals by flushing them down the toilet or
discarding them to the trash. Household quantities of
expired or waste pharmaceuticals may be mixed with wet
cat litter or coffee grounds, double-bagged in plastic, discard in trash. Larger quantities shall carefully take into consideration applicable DEA, EPA, and FDA regulations. If
possible return the pharmaceutical to the manufacturer for
proper disposal being careful to properly label and securely
package the material. Alternatively, the waste pharmaceutical shall be labeled, securely packaged, and transported by
a state licensed medical waste contractor to dispose by
burial in a licensed hazardous or toxic waste landfill or
incinerator.
Check Digit Verification of cas no
The CAS Registry Mumber 51-83-2 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 5 and 1 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 51-83:
(4*5)+(3*1)+(2*8)+(1*3)=42
42 % 10 = 2
So 51-83-2 is a valid CAS Registry Number.
