Applications

2-Nitrobenzaldehyde is used as a starting material in synthetic chemistry. It is used as an intermediate during the synthesis of Indigo dye. It is involved in the preparation of colorants such as Indigo carmine. Further, it serves as a useful photoremovable protecting group as well as utilized in the preparation of o-nitrophenylethylene glycol.

Notes

Incompatible with strong oxidizing agents and strong bases.

Literature References

The nitro group can be displaced by nucleophiles. Thus, tert-butanethiol gives 2-tert-butylthiobenzaldehyde, a useful intermediate for thiocoumarins and other sulfur-containing heterocycles: Synthesis, 56 (1978).
