tert‑Butyl Chloride is a tertiary alkyl halide supplied as a chemical raw material, also known as 2‑chloro‑2‑methylpropane or chlorinated tert‑butane in technical documentation. Identified by CAS 507‑20‑0, its tertiary carbon–chlorine bond structure makes it highly reactive in substitution and elimination reactions under controlled conditions. It is typically applied as an organic intermediate in industrial synthesis processes where controlled carbocation formation and alkylation behavior 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.

Product Description
Chlorinated tert-butane
also known as 2-chloro-2-methylpropane; tert-butyl chloride; Chloro-tert-butane
Chlorinated tert-butane is a chemical substance with the molecular formula (CH3)3CCl. Colorless liquid. It is insoluble in water and miscible with ethanol and ether. It is flammable and releases toxic phosgene when exposed to high heat. It reacts strongly with oxidizing agents and burns immediately in open flame. It is more toxic than 1-chlorobutane.

storage and transportation method
of organic raw materials Storage precautions: Store in a cool and ventilated warehouse. Stay away from fire and heat sources. The storage temperature should not exceed 30°C. It should be stored separately from oxidants and alkalis, and should not be mixed. Explosion-proof lighting and ventilation facilities are adopted. It is forbidden to use mechanical equipment and tools that are prone to sparks. The storage area should be equipped with leakage emergency treatment equipment and suitable containment materials
Packaging method: small opening steel drum; Ordinary wooden box outside the ampoule; Threaded glass bottles, iron-capped press-mouth glass bottles, plastic bottles or ordinary wooden boxes outside metal barrels (cans).
FAQ - Technical & Supply Chain
-
Q:
Are tert‑butyl chloride and 2‑chloro‑2‑methylpropane the same substance?
A: Yes. 2‑Chloro‑2‑methylpropane is the systematic IUPAC name for tert‑butyl chloride, and both correspond to CAS 507‑20‑0. -
Q:
Is tert‑butyl chloride different from n‑butyl chloride or isobutyl chloride?
A: Yes. These compounds are structural isomers with different carbon skeletons and reactivity profiles and are assigned different CAS numbers. -
Q:
Is tert‑butyl chloride mainly supplied as an industrial intermediate?
A: It is commonly supplied as an organic intermediate for controlled industrial synthesis rather than as a finished end‑use product.
