Specification

The 2,5-Dichlorotoluene, with the CAS registry number 19398-61-9, is also known as Toluene, 2,5-dichloro- (8CI). It belongs to the product categories of Aromatic Hydrocarbons (substituted) & Derivatives; Organics; Halogen toluene; Chlorine Compounds; Aryl; C7; Halogenated Hydrocarbons; Alpha Sort; Analytical Standards; Aromatics Chemical Class; Chemical Class; ChloroVolatiles/ Semivolatiles; D; D Alphabetic; Halogenated. Its EINECS number is 243-032-2. This chemical's molecular formula is C₇H₆Cl₂and molecular weight is 161.03. What's more, its systematic name is 1,4-Dichloro-2-methylbenzene. This chemical is stable at common pressure and temperature, and it should be sealed and stored in a cool, ventilated and dry place. Moreover, it should be protected from oxides, heat and fire. It is used as a solvent and an organic synthesis intermediate. Taking o-chlorotoluene as raw material, 2,5-Dichlorotoluen is synthesized via catalytic chlorination process.
