Manufactured by Shanghai Wechem Technology, this Carbonyl Sulfide (COS, CAS 463-58-1) is supplied at 99.8% purity as a flammable compressed gas (UN2204), used as an intermediate in thiocarbamate herbicide production and as a potential fumigant alternative to methyl bromide and phosphine, though the supplier notes it can leave residues affecting flavor in grain used for brewing. It is offered in pharmaceutical grade and sold across North America, Europe, Australasia, Asia, the Middle East, and Africa.
