Description

🧪 1,2,4,5-Tetrachloro-3-nitrobenzene (TCNB)

Chemical Name: 1,2,4,5-Tetrachloro-3-nitrobenzene
CAS Number: 117-18-0
Molecular Formula: C₆Cl₄NO₂
Molecular Weight: 260.88 g/mol
Synonyms: TCNB, Tetrachloronitrobenzene, 3-Nitro-1,2,4,5-tetrachlorobenzene
Chemical Category: Chlorinated Nitroaromatic Compound

🔍 Product Overview:

1,2,4,5-Tetrachloro-3-nitrobenzene (TCNB) is a chlorinated aromatic compound widely used as an intermediate in organic synthesis. Its electron-withdrawing substituents (four chlorine atoms and one nitro group) make it a highly reactive platform for further chemical transformations, particularly in the production of agrochemicals, dyes, pharmaceuticals, and specialty polymers.

Thanks to its stability and distinctive substitution pattern, TCNB is also of interest in chemical research, where it's used in studying aromatic substitution mechanisms and structure-reactivity relationships.

🏭 Primary Applications:

🔬 Intermediate in agrochemical synthesis (used in herbicide and fungicide production)
🎨 Precursor in dye manufacturing
💊 Pharmaceutical intermediate for nitroaromatic drug development
🧱 Building block in polymer and materials science
🧪 Reference standard and research chemical for halogenated aromatic studies
