01 · Identification
What Thiocarbonyl chloride is
Thiocarbonyl chloride is a reddish liquid with a sharp choking odor. Its molecular formula is CCl2S and its molecular weight is 114.98 g/mol. It boils at 73 °C, is practically insoluble in water.
Under the GHS it carries the signal word Danger. It is classed as corrosives.

04 · Handling and storage
Storing and handling Thiocarbonyl chloride
Incompatible materials
Reactivity with water: Evolves hydrogen chloride, carbon disulfide, & carbon dioxide. Reaction is slow unless water is hot.
Source: Hazardous Substances Data Bank (HSDB)
Reactivity
THIOPHOSGENE is incompatible with acids, diazo and azo compounds, halocarbons, isocyanates, aldehydes, alkali metals, nitrides, hydrides, and other strong reducing agents. Reactions with these materials generate heat and in many cases hydrogen gas. Liberates hydrogen sulfide upon reaction with acids.

Safety Data Sheet
Getting an SDS for Thiocarbonyl chloride
A Safety Data Sheet is written for a product, not for a substance: the supplier of the grade you actually buy issues it, so two suppliers of Thiocarbonyl chloride issue two different sheets. That is why there is no single authoritative SDS for a substance to download — what there is, is the job of collecting the sheets for the products you hold and keeping them current as suppliers revise them.
