Bis(2-chloroethyl) ether CAS 111-44-4
High-Purity Bis(2-chloroethyl) Ether CAS 111-44-4 from Aure Chemical: Stable Supply & Compliance
Bis(2-chloroethyl) ether is a colorless chlorinated ether with a characteristic solvent odor. It is used as a reactive intermediate and as a process solvent, and it must be handled as a highly toxic, combustible liquid. Aure Chemical supplies Bis(2-chloroethyl) ether (CAS 111-44-4) to industrial and synthesis customers who need documented quality and Class 6.1 transport paperwork.

Key Applications of Bis(2-chloroethyl) Ether
Chemical intermediate: The principal industrial use is as a bifunctional chloroethyl ether building block for further organic synthesis, including pesticide intermediates and other chlorinated derivatives.
Process and extraction solvent: It has been used as a selective solvent for oils, resins and related organics, including lubricating-oil treating and extraction of fats where a chlorinated ether medium is specified.
Crown-ether and specialty synthesis: In the presence of base it is used with catechol to prepare dibenzo-18-crown-6 and related macrocycles, and it appears in other ring-forming or alkylating sequences.
Coatings and textile process chemistry: Smaller volumes have been used in paints, varnishes, lacquers, finish removers and textile scouring or fulling formulations that require a chlorinated ether solvent.
Crosslinking and downstream organics: The two chloroethyl groups allow use as a crosslinking or alkylating intermediate in selected polymer-related and fine-chemical routes.
Aure Chemical: Your Reliable Partner for Bis(2-chloroethyl) Ether Supply
Assay-controlled toxic intermediate quality: Lots are supplied against defined purity expectations so synthesis users receive a consistent chloroethyl ether rather than a peroxide-aged or off-spec material.
Class 6.1 dual-hazard logistics: Export is coordinated through channels experienced with UN 1916 packing, subsidiary Class 3 risk and destination rules for this toxic, combustible liquid.
SDS and high-toxicity documentation: SDS, COA and dangerous-goods papers are available to support industrial purchasing, incoming QA and regulatory handling of this acutely toxic ether.
Sealed-pack and peroxide-check guidance: Assistance is available on tight containers, storage away from light and air, and shipment planning from research packs to larger industrial quantities.
Hazards Classification
GHS Classification: Flammable liquid (Category 3, GHS02); Acute toxicity, oral, dermal and inhalation (Category 1/2, GHS06); Carcinogenicity (Category 2, GHS08). Harmonized CLP labelling identifies the substance as fatal if swallowed, in contact with skin or if inhaled, and suspected of causing cancer.
Hazard Statements: H226 Flammable liquid and vapor; H300 + H310 + H330 Fatal if swallowed, in contact with skin or if inhaled; H351 Suspected of causing cancer. The liquid can form peroxides on exposure to air and light and decomposes to hydrogen chloride on burning or contact with water.
UN Number: UN 1916 (2,2'-DICHLORODIETHYL ETHER)
Hazard Class: 6.1 (Toxic substances), subsidiary risk 3 (Flammable liquid)
