2-nitro benzoic acid-d4

2-nitro benzoic acid-d4 is a deuterated version of 2-nitro benzoic acid, which is a common organic compound. It is used as a starting material in the synthesis of various drugs, dyes, and pigments. The deuterated version, 2-nitro benzoic acid-d4, is used as a reference standard in nuclear magnetic resonance (NMR) studies. The chemical formula of 2-nitro benzoic acid-d4 is C7D4NO4, and it has a molecular weight of 184.15 g/mol. It is a pale yellow crystalline powder with a melting point of 240-243°C. The solubility of 2-nitro benzoic acid-d4 in water is low, but it is soluble in organic solvents such as ethanol, acetone, and chloroform. The presence of deuterium in 2-nitro benzoic acid-d4 makes it useful for NMR studies, as it provides a clearer and more precise signal compared to the non-deuterated version. The NMR spectrum of 2-nitro benzoic acid-d4 can be used to determine the structure and purity of other compounds. In terms of safety, 2-nitro benzoic acid-d4 is a hazardous substance and should be handled with care. It may cause skin and eye irritation, and inhalation of its dust or vapors may cause respiratory irritation. It should be stored in a cool, dry, and well-ventilated area away from heat sources and incompatible materials.
