Dicofol is an organochlorine pesticide that is chemically related to DDT. Dicofol is a miticide that is very effective against spider mite. Its production and use is banned internationally under the Stockholm Convention. One of the intermediates used in its production is DDT. This has caused criticism by many … See more Dicofol is structurally similar to DDT. It differs from DDT by the replacement of the hydrogen (H) on C-1 by a hydroxyl (OH) functional group. One of the intermediates used in its production is DDT. See more Dicofol is usually synthesized from technical DDT. During the synthesis, DDT is first chlorinated to an intermediate, Cl-DDT, followed by … See more Foliar spray on agricultural crops and ornamentals, and in or around agricultural and domestic buildings for mite control.

This often results in poor recoveries and poor analytical precision. The use of isotope-labeled dicofol (e.g. dicofol-D8) as internal standard (ILIS) is the most efficient and convenient way to eliminate most sources of errors. can cells survive without oxygen
