Novel pyridine compounds having the formula R.sup.1 -S-S-A-Z are disclosed, in which formula R.sup.1 is 2-pyridyl, 5-nitro-2-pyridyl or 4-pyridyl, A is a hydrocarbon residue having 1-10 carbon atoms and Z is a group ##STR1## or acid addition salts of the last mentioned group, where n is 2 or 3, R.sup.1 has the same significance as R.sup.1 above and is equal thereto and R.sup.2 is methyl or ethyl. These compounds are particularly useful as bifunctional coupling agents and as thiolating agents.
