Product Description

tert-Butyl Chloride, CAS 507-20-0, is 2-chloro-2-methylpropane. Molecular formula: C₄H₉Cl; EC Number: 208-066-4. tert-Butyl Chloride is not n-butyl chloride or isobutyl chloride; the requested isomer must be identified by name and CAS. This page does not confirm a fixed grade, package, stock position, transport condition or application claim. For an RFQ, state the exact isomer, required analytical limits and intended synthesis context, quantity, packaging, destination and document requirements; use the current product-specific SDS and specification for safety review.

FAQ - Technical & Supply Chain

  • Q:

    Are tert-Butyl Chloride and t-Butyl Chloride the same material?

    A: Yes. tert-butyl chloride, t-butyl chloride and 2-chloro-2-methylpropane identify CAS 507-20-0. They are not n-butyl chloride, isobutyl chloride or sec-butyl chloride. State the exact isomer, CAS number and analytical limits on the order.
  • Q:

    What is tert-Butyl Chloride used for?

    A: It is used as a tertiary alkyl chloride intermediate in controlled organic synthesis. State the intended synthesis context, required assay and impurity limits, because performance can depend on the presence of isobutylene, tert-butanol or other chlorinated impurities.
  • Q:

    Which specifications should be agreed for industrial tert-Butyl Chloride?

    A: Set assay by GC, water, acidity, colour, nonvolatile residue and limits for isobutylene, tert-butanol and other chlorinated impurities. Because the compound is volatile and moisture-sensitive, define pressure, density and sampling conditions where applicable.
  • Q:

    What safety and handling points should be reviewed?

    A: Confirm the compound's high volatility and flammability, with a boiling point around 51-52 degrees C and low flash point. Use suitable ventilation, container compatibility, static control and disposal procedures before sampling or transfer, and avoid treating it as interchangeable with other butyl chlorides.
  • Q:

    What information should an RFQ include for tert-Butyl Chloride?

    A: State the exact isomer and CAS, required analytical limits, intended synthesis context, quantity, packaging, destination and document requirements. Confirm packaging for the offered material and destination before quotation.
