Description and Uses
2-Nitrobenzaldehyde (2-NBA) is a multifunctional compound used in dyes, pharmaceuticals, food, and organic synthesis. Due to its distinctive yellow crystalline appearance, 2-NBA is used as an intermediate in the synthesis of indigo dyes. It is also used in the synthesis of 2-Nitrobenzyl-chitosan and nifedipine. Furthermore, 2-NBA can be used as a preservative in meat products, for the preservation of meat and food (preventing light damage), and has applications in the packaging industry.
2-Nitrobenzaldehyde is a benzaldhyde with a nitro group substituted in the ortho position. 2-Nitrobenzaldehyde is used in the preparation of dyes and colorants such as Indigo carmine. 2-Nitrobenzaldehyde gas been shown to be a useful photoremovable protecting group as well as in the preparation of more effective ones such as o-Nitrophenylethylene glycol.
