04 · Handling and storage
Storing and handling Ethyl p-nitrophenyl…
Storage conditions
Keep away from heat and open flame. Keep container closed. Store at 65-100 °F.
Source: Hazardous Substances Data Bank (HSDB)
Incompatible materials
Strong oxidizers
Source: Hazardous Substances Data Bank (HSDB)
Reactivity
Organophosphates, such as EPN, are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides.

Safety Data Sheet
Getting an SDS for Ethyl p-nitrophenyl…
A Safety Data Sheet is written for a product, not for a substance: the supplier of the grade you actually buy issues it, so two suppliers of Ethyl p-nitrophenyl… issue two different sheets. That is why there is no single authoritative SDS for a substance to download — what there is, is the job of collecting the sheets for the products you hold and keeping them current as suppliers revise them.
