Chlorinating quinolin-8-ol yields a mixture, generically called halquinol, which contains 5,7-dichloroquinolin-8-ol (5,7-DCL; 57-74 % w/w), 5-chloroquinolin-8-ol (5-CL; 23-40 % w/w) and 7-chlorquinolin-8-ol (7-CL; 0-4 % w/w). Halquinol 60% premix is composed of chlorohydroxyquinoline (halquinol; 60 % w/v), and chalk (calcium carbonate; to 100 % w/v).
