Use
M-chlorobenzaldehyde is an intermediate of the plant growth regulator ripening ester. Used as medicine, dye intermediates. The pesticides produced from o-chlorobenzaldehyde can be used to control aphids on dry crops and fruit trees. O-chlorobenzaldehyde can be obtained by o-chlorobenzidine, and further chlorination can obtain o-chlorobenzidine, which are all pharmaceutical intermediates. Used as dyes, pesticides, pharmaceutical intermediates
