Disinfectant no help with dislocation (6)

I believe the answer is:

phenol

I'm a little stuck... Click here to teach me more about this clue!

'disinfectant' is the definition.
(I've seen this before)

'no help with dislocation' is the wordplay.
'no help' anagrams to 'PHENOL'.
However, I am not sure how the anagram is indicated.

Can you help me to learn more?

(Other definitions for phenol that I've seen before include "Acidic substance" , "No help (anag) - antiseptic" , "Carbolic acid" , "Powerful disinfectant" , "cleaner" .)
