Where EUH044 is current
GHS is a United Nations model text, revised every two years, and each jurisdiction adopts a revision on its own timetable. A code can be legally current in one system and deleted in another — that is normal, not an error.

Substances carrying EUH044
Every entry whose harmonised CLP Annex VI classification includes this hazard statement. Substances with a reference page here open on this site; the rest open on ghssymbols.com. Of these, 1 is a group entry such as “salts of picric acid” or “beryllium compounds” — Annex VI gives them no CAS number, so they are listed by Index No and have no page of their own.
- dinoseb (ISO); 6-sec-butyl-2,4-dinitrophenol CAS 88-85-7
- dinoterb (ISO); 2-tert-butyl-4,6-dinitrophenol CAS 1420-07-1
- DNOC (ISO); 4,6-dinitro-o-cresol CAS 534-52-1
- salts and esters of dinoseb, with the exception of those specified elsewhere in this Annex Index No 609-026-00-2
Nothing matches that filter.
