2,4-Dinitrophenol (2,4-DNP or simply DNP) is an organic compound with the formula HOC 6 H 3 (NO 2) 2. It has been used in explosives manufacturing and as a pesticide and herbicide. In humans, DNP causes dose-dependent mitochondrial uncoupling , causing the rapid loss of ATP as heat and leading to uncontrolled hyperthermia —up to 44 °C (111 ...

2,4-Dinitrophenylhydrazine (2,4-DNPH or DNPH) is the organic compound C 6 H 3 (NO 2) 2 NHNH 2. DNPH is a red to orange solid. It is a substituted hydrazine. The solid is relatively sensitive to shock and friction. For this reason DNPH is usually handled as a wet powder. DNPH is a precursor to the drug Sivifene.
A solution of 4-nitrophenol appears colorless below pH 5.4 and yellow above pH 7.5. [3] This color-changing property makes this compound useful as a pH indicator. The yellow color of the 4-nitrophenolate form (or 4-nitrophenoxide) is due to a maximum of absorbance at 405 nm (ε = 18.3 to 18.4 mM −1 cm −1 in strong alkali). [4]
o-Nitrophenol (2-nitrophenol; OH and NO 2 groups are neighboring, a yellow solid. m-Nitrophenol (3-nitrophenol, CAS number: 554-84-7), a yellow solid (m.p. 97 °C) and precursor to the drug mesalazine (5-aminosalicylic acid). It can be prepared by nitration of aniline followed by replacement of the amino group via its diazonium derivative. [2]
The Bogor Zoological Museum has an area of 1,500 m 2 (16,000 sq ft), [2] and contains one of the most extensive fauna collections in Southeast Asia. There are 24 rooms in the museum, which are maintained at a constant temperature of 22 °C (72 °F) to help protect the exhibits in its collection.
2,4-Di-tert-butylphenol (2,4-DTBP) is a white solid with a phenolic odour. It is primarily used as a raw material for the production of several commercially important antioxidants and phenolic benzotriazole -type UV absorbers .
