    4‑Chlorotoluene CAS 106‑43‑4

    4‑Chlorotoluene is an aromatic chlorinated hydrocarbon supplied as a chemical raw material, also known as p‑chlorotoluene or 1‑chloro‑4‑methylbenzene in technical documentation. Identified by CAS 106‑43‑4, its para‑substituted benzene structure enables selective downstream functionalization through substitution, oxidation, and coupling reactions in controlled synthesis systems. It is typically applied as an organic intermediate in industrial chemical manufacturing processes where positional isomer purity and predictable reactivity are required. From a supply perspective, the material is available with competitive factory pricing, customized specifications, and supporting documentation including MSDS, TDS, COA, suitable for regulated bulk supply for industrial use.

    Uses
    This product is an organic synthetic raw material used in pharmaceuticals, pesticides, dyes, organic synthesis intermediates, and solvents for rubber and synthetic resins. It is the main raw material for the preparation of p-chlorosubzyl trifluoro, p-chlorobenzyl chloride, p-chlorobenzaldehyde, p-chlorobenzoyl chloride and p-chlorobenzoic acid. It is an intermediate for the preparation of cypermethrin, paclozol, enazole and pesticides such as flurolin, grass dan, and paraben. p-chlorobenzaldehyde can also be manufactured, which is used as a dye and pharmaceutical intermediate; Manufacture p-chlorobenzoyl chloride, which is an intermediate in pharmaceutical anti-inflammatory drugs; Manufactures p-chlorobenzoic acid, which is a raw material for dyes and textile finishing agents.

    FAQ - Technical & Supply Chain

    • Q:

      Are 4‑chlorotoluene and p‑chlorotoluene the same substance?

      A: Yes. 4‑Chlorotoluene and p‑chlorotoluene are different naming conventions for the same compound corresponding to CAS 106‑43‑4.
    • Q:

      Is 4‑chlorotoluene different from o‑chlorotoluene or m‑chlorotoluene?

      A: Yes. These are positional isomers with different substitution patterns on the aromatic ring and are treated as distinct substances with separate CAS numbers.
    • Q:

      Is 4‑chlorotoluene mainly supplied as an industrial intermediate?

      A: It is commonly supplied as a chemical intermediate for industrial synthesis rather than as a finished end‑use product.
