CAS No. 139-07-1 refers to a specific chemical compound.

Understanding CAS No. 139-07-1 The Chemical Identity and Significance CAS (Chemical Abstracts Service) Registry Numbers are unique identifiers assigned to chemical substances, enabling the accurate and consistent referencing of chemicals across various scientific disciplines. CAS No. 139-07-1 refers to a specific compound with distinct properties and applications. This article aims to delve into the details of this chemical entity. CAS No. 139-07-1 corresponds to the compound known as 2,4-Dinitrophenol (2,4-DNP). It is an organic compound, classified under the broader category of nitrophenols, which are aromatic compounds derived from phenol by the substitution of one or more hydroxyl groups with nitro groups. First synthesized in the late 19th century, 2,4-DNP has a rich history in chemical research and industrial applications. 2,4-Dinitrophenol is a yellow, crystalline solid that dissolves readily in polar solvents like water and alcohol. Its distinctive chemical structure, with two nitro groups attached to the ortho positions of the benzene ring, imparts it with unique chemical reactivity. It exhibits acidic properties due to the presence of nitro groups, making it useful as a reagent in chemical reactions. Historically, 2,4-DNP was employed as a dye intermediate, contributing to the vibrant colors in textiles and other products Historically, 2,4-DNP was employed as a dye intermediate, contributing to the vibrant colors in textiles and other products

cas no 139 07 1. However, its significance expanded when it was discovered to have metabolic effects. In the early 20th century, it was briefly used as a weight-loss drug due to its ability to uncouple oxidative phosphorylation, effectively increasing metabolism. However, due to severe side effects, including high fever, cataracts, and even fatalities, its use was quickly discontinued. Today, 2,4-DNP primarily finds application in the manufacturing of dyes, explosives, and pharmaceutical intermediates. Despite its historical medicinal use, its hazardous nature and potential health risks have limited its application in modern times. It is considered a toxic substance and is regulated accordingly to ensure safe handling and disposal. In conclusion, CAS No. 139-07-1, representing 2,4-Dinitrophenol, is a chemical compound with a multifaceted history. While it once held promise in pharmaceuticals, its toxicity has shifted its primary use to industrial processes. As with all chemicals, understanding its properties, uses, and risks is crucial for responsible scientific inquiry and industrial practice. The CAS Registry Number system plays a vital role in this endeavor, providing a universal language for identifying and tracking substances in the complex world of chemistry.
