    Product Description

    4-Chlorotoluene, CAS 106-43-4, is the para chlorotoluene isomer. Synonyms: 4-Chlorotoluene; p-Chlorotoluene; 1-Chloro-4-methylbenzene. Molecular formula: C₇H₇Cl; EC Number: 203-397-0.

    4-Chlorotoluene is the same entity as p-chlorotoluene and must be distinguished from the ortho and meta isomers. This page does not confirm a fixed purity, package, document availability or downstream application. For an RFQ, state the para-isomer identity, required analytical limits and intended technical process.













    FAQ - Technical & Supply Chain

    • Q:

      Are 4-Chlorotoluene and p-Chlorotoluene the same isomer?

      A: Yes. 4-chlorotoluene and p-chlorotoluene identify the para isomer, CAS 106-43-4. They are not 2-chlorotoluene, 3-chlorotoluene or benzyl chloride. State the para isomer, CAS number and liquid industrial grade in the purchasing specification.
    • Q:

      What is 4-Chlorotoluene used for?

      A: It is a para-substituted aromatic intermediate for controlled organic synthesis. Downstream suitability depends on the intended technical process, so the route, isomer purity requirement and impurity tolerance should be stated rather than relying on a generic product description.
    • Q:

      Which specifications matter when purchasing industrial 4-Chlorotoluene?

      A: Agree assay by GC, water, colour, distillation range, acidity, nonvolatile residue and limits for the ortho and meta isomers. A typical industrial release also controls benzene and other aromatic impurities, so confirm the test methods before shipment.
    • Q:

      What safety and handling points should be reviewed?

      A: Confirm the material's flammability, with a boiling point around 162 degrees C and flash point roughly 53 degrees C. Use suitable ventilation, personal protection and spill controls before transfer, and keep the liquid in a closed container away from ignition sources and incompatible materials.
    • Q:

      What information should an RFQ include for 4-Chlorotoluene?

      A: State the para-isomer identity, required analytical limits, intended technical process, quantity and destination. Confirm packaging for the offered material and document requirements with the quotation.
