WebNov 7, 2016 · First, a note on nomenclature. You’ve probably seen 2,4-dinitrophenylhydrazine referred to alternately as 2,4-DNPH or 2,4-DNP. Strictly speaking, the former is more correct, though the latter is commonly used to refer to it too. However, 2,4-DNP can also refer to 2,4-dinitrophenol, which isn’t the specific chemical being … DNP is considered to have high acute toxicity. In March 2024 a UK judge stated "there is no antidote or remedy for DNP once taken. In consequence, DNP has a high mortality rate ⁠— ⁠of those who presented at hospital between 2007 and 2024 with a history of having taken DNP, 18% died. This puts DNP close to cyanide in terms of its toxicity." The study published in 2024 indicates that the worldwide cases fatality overall was 11.9% between 2010 and 2024.
