3-Nitrophenol is an aromatic organic compound characterized by a nitro group (-NO₂) attached to a phenol ring, primarily used as an intermediate in the synthesis of dyes, pharmaceuticals, and agrochemicals. It also serves as a precursor in the production of herbicides and explosives. Laboratories also use it as an acid-base indicator for slightly basic solutions, changing from colorless to yellow between roughly pH 6.8 and 8.6. This yellow crystalline solid has a CAS number of 554-84-7, with the molecular formula O₂NC₆H₄OH and a molecular weight of 139.11 g/mol. It is stable under ambient storage conditions but requires careful handling due to its hazardous nature, marked by the signal word "Danger." Molekula supplies 3-Nitrophenol from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
