Transport Information
Appearance colourless gas with an unpleasant smell; cylinderwill be marked with red/yellow bands at valve end to denote contentsare both flammable and toxic
Safety Poison by intraperitoneal route. Mildly toxic by inhalation. Narcotic in high concentration. An irritant. May liberate highly toxic hydrogen sulfide upon decomposition. A very dangerous fire hazard and moderate explosion hazard when exposed to heat or flame. Can react vigorously with oxidizing materials. To fight fire, stop flow of gas or use CO₂, dry chemical, or water spray. When heated to decomposition it emits toxic fumes of CO. See also CARBONYLS and SULFIDES.
Risk Codes R11; R20; R36/37/38
Molecular Structure
Hazard Symbols Narcotic in high concentrations. Flammable, explosive limits in air 12–28.5%.
Synonyms Carbonylsulfide (8CI); Carbon monoxide monosulfide; Carbon oxide sulfide; Carbonoxysulfide; Carbon oxysulfide (COS); Carbonyl sulfide (COS); OCS; Oxycarbonsulfide (COS); Thiocarbonyl oxide

CARBONYL SULFIDE Chemical Properties

MF: COS
MW: 60.08
EINECS: 207-340-0
mp: 138 °C(lit.)

form: gas
Carbonyl sulfide is the chemical compound with the formula OCS. Commonly written as COS, it is a colourless flammable gas with an unpleasant odor. It is a linear molecule consisting of a carbonyl group double bonded to a sulfur atom. Carbonyl sulfide can be considered to be intermediate between carbon dioxide and carbon disulfide, both of which are isoelectronic with it.

CARBONYL SULFIDE Uses

1、Carbonyl sulfide is used as an intermediate in the production of thiocarbamate herbicides.Carbonyl sulfide is a potential fumigant and a replacement for methyl bromide and phosphine.
2、Carbonyl sulfide's primary use as a chemical intermediate and as a byproduct of carbon disulfide production.
3、It is also a significant sulfur-containing impurity in synthesis gas.

CARBONYL SULFIDE Toxicity Data With Reference

1、As of 1994, there was limited information on the acute toxicity of carbonyl sulfide in humans and in animals.High concentrations (>1000 ppm) can cause sudden collapse, convulsions, and death from respiratory paralysis.
2、In tests with rats, 50% animals died when exposed to 1400 ppm of COS for 90 minutes, or at 3000 ppm for 9 minutes.Limited studies with laboratory animal studies also suggest that continued inhalation of low concentrations (approximately 50 ppm for up to 12 weeks) does not affect the lungs or the heart.

CARBONYL SULFIDE Safety Profile

Hazard Codes： F,Xn
Risk Statements： 11-20-36/37/38
Safety Statements： 16-26-38
RIDADR： UN 2204 2.3
WGK Germany： 3
RTECS： FG6400000
HazardClass： 2.3
Poison by intraperitoneal route. Mildly toxic by inhalation. Narcotic in high concentration. An irritant. May liberate highly toxic hydrogen sulfide upon decomposition. A very dangerous fire hazard and moderate explosion hazard when exposed to heat or flame. Can react vigorously with oxidizing materials. To fight fire, stop flow of gas or use CO₂, dry chemical, or water spray. When heated to decomposition it emits toxic fumes of CO.
