2,4-DNP 2,4-dinitrophenylhydrazine Disposal

Due to some high profile incidents and controlled explosions at several schools, all holders of stocks of 2,4-DNP (2,4-dinitrophenylhydrazine,)are being reminded to check the storage arrangements for this chemical as per Hazcard 30.



As long as the waste has been stored correctly, this chemical is perfectly safe, but some schools are reporting the deterioration and drying out of the product over time which could produce issues.



It is very important to ensure this  product is kept damp and we would also advise not storing this or any other chemistry for a period of longer than 10 years before replenishing your stocks. This period is only a guideline as in our experience containers, labels and sometimes the chemistry itself can deteriorate in time. For further advise on this please contact your manufacturer or CLEAPSS.

Should you wish to safely dispose of your 2,4-DNP 2,4-dinitrophenylhydrazine, so long as the product is still wet, we can collect this for you on its own or together with any other unwanted lab waste.

We offer a nationwide 2,4-DNP 2,4-dinitrophenylhydrazine disposal service, are CLEAPSS associate members and fully licensed by the Environment Agency.
