Yellow to brown crystalline powder
1-Nitro-2-naphthaldehyde (NAA) may be used to prepare the precursors required for the preparation of 3-acetoxy-2-methylene-3-(1-nitronaphth-2-yl)propanoate and ethyl 3-acetoxy-2-methylene-3-(1-nitronaphth-2-yl)propanoate.
On irradiation with UV light, 1-nitro-2-naphthaldehyde gets transformed into the corresponding nitroso acid.
