2-Nitrodiphenylamine
2-Nitrodiphenylamine(2-NPE)
2-Nitrodiphenylamine, tseem hu ua NDPA, 2-NDPA, 2NO2DPA, Sudan Yellow 1339, CI 10335, CI 10335, phenyl 2-nitrophenylamine, 2-nitro-N-phenylaniline, los yog N-phenyl-o-nitroaniline, yog ib qho tshuaj organic, nitrated. aromatic amine, ib tug derivate ntawm diphenylamine.
2-Nitrodiphenylamine yog ob lub hauv paus (DB) foob pob hluav taws tiv thaiv stabilizer thiab nws cov microencapsulation muaj peev xwm txhim kho lub txee lub neej ntawm DB foob pob hluav taws.
Nws yog liab crystalline khoom, feem ntau nyob rau hauv daim ntawv ntawm flakes los yog hmoov, nrog yooj yim sublimation khoom.
