Monoethylene glycol (MEG), CAS 107-21-1, is a clear, colourless, water-miscible liquid used in polyester production and industrial antifreeze and heat-transfer formulations.
For industrial purchasing, match the required specification to the application. Send us your intended use and quantity to discuss a quotation, packing and supporting documents.
Monoethylene glycol (MEG), CAS 107-21-1, is a diol feedstock used with purified terephthalic acid (PTA) in PET manufacture. Applications include polyester fibres, films and packaging resins. Agree the raw-material specification for your polymerisation process before ordering.
MEG is used as a raw material in glycol-based industrial fluids. Select the formulation, water quality and corrosion-inhibitor system for the equipment and operating conditions. Raw MEG should not be treated as a ready-to-use inhibited coolant.
Propylene glycol is a different chemical used in other glycol-based formulations. Triethylene glycol (TEG) is another glycol with a distinct identity and process role. Choose by application and specification; these materials are not interchangeable simply because they share the word “glycol”.
Use an agreed specification for purchasing rather than a generic purity claim. Your enquiry can identify the required assay, water content, colour and any process-sensitive impurity limits. Where limits are specified, state the units and test methods so that the quotation and quality documents use the same basis.

Identity and general physical properties describe the substance. They are not a batch analysis or a guaranteed numerical purchase specification.
Drums, IBCs and bulk transport are established industry formats for MEG. Tell us your receiving facilities and preferred format; the applicable packing and shipment details will be confirmed with the quotation. The packaging illustration does not specify a net weight.
MEG is hygroscopic. Keep containers closed and avoid moisture or foreign-material contamination. Use the applicable Safety Data Sheet for handling, protective equipment, storage compatibility and disposal requirements.
We can provide a Certificate of Analysis (COA), Technical Data Sheet (TDS) and Safety Data Sheet (SDS) for product evaluation and order documentation. A batch COA should be assessed against the specification agreed for that order.
Key information for document requests, quotations, and supply planning.
Tell us which documents your procurement team needs. Before an order, we will check whether the quoted source can provide them for the offered lot.
Send the CAS number, grade, quantity, packing preference and destination.
Ask whether samples, trial quantities or repeat orders are possible. We will check each request against the sourced product and current offer.
Product-specific conditions are confirmed before order.
