    Sourcing guidance

    Buyer's checklist for MEA in bulk

    Sourcing 2-ethyl-6-methylaniline for a European plant is more than comparing price per kg. Use this list to evaluate any supplier.

    • Confirm CAS 24549-06-2 and isomer identity on the COA
    • Request GC purity, water content, colour (APHA/Pt-Co) and impurity profile
    • Verify REACH registration status and who acts as importer of record for EU entry
    • Compare landed cost by Incoterm: FOB, CFR, CIF or DAP to your facility
    • Qualify a lab sample before committing to a full drum, IBC or ISO tank order
    • Confirm dangerous-goods packing, CLP labelling and licensed forwarder details

    End-to-end logistics

    We book freight through licensed DG forwarders, manage customs documentation and coordinate delivery to your nominated port or plant. No need to deal with multiple parties.

    REACH & regulatory support

    We confirm REACH registration status before quoting and advise on importer-of-record arrangements for EU market entry. Your procurement team gets clear answers, not ambiguity.

    It is also sold as 2-ethyl-6-methylaniline, 2-methyl-6-ethylaniline, 6-ethyl-o-toluidine and MEA. All refer to CAS 24549-06-2. Confirm the CAS number with any supplier before ordering to avoid receiving the wrong isomer.

    Price depends on grade, order volume, packing, Incoterm and destination port, and it moves with raw material markets. Send us your requirement and we will quote in EUR or USD with a clear landed-cost breakdown — usually within one business day.

    Yes. 2-Ethyl-6-methylaniline is a recognised aniline building block for chloroacetanilide herbicides such as acetochlor and metolachlor. Your process chemists should confirm the grade, purity level and impurity limits their synthesis requires.

    Standard grade offers ≥ 98.0% GC purity and APHA colour ≤ 50. Premium grade offers ≥ 99.0% GC purity, APHA ≤ 20, lower water content (≤ 0.2% KF) and nitrogen-blanketed packaging to prevent oxidative darkening. Premium is recommended for high-yield or multi-step synthesis routes where impurity profiles are tightly controlled.

    Keep it in tightly closed original UN-approved containers, away from light, air, heat, oxidisers and acids. Aromatic amines can darken on prolonged exposure to air. Use within the shelf life stated on the COA and TDS, and store in a well-ventilated, cool area.

    Yes. We supply laboratory and pilot-scale samples supplied with a certificate of analysis (COA) and safety data sheet (SDS) so your team can qualify the grade before scaling up to drums, IBCs or ISO tanks. Ask about sample availability when you submit your enquiry.

    Yes — it is classified as a dangerous good (UN 2810, Class 6.1, Packing Group III). We pack it in UN-approved containers, apply CLP-compliant labels and ship exclusively through licensed dangerous-goods forwarders under IMDG for sea freight and ADR for European road transport.

    A standard shipment includes: bill of lading, commercial invoice, packing list, certificate of analysis (COA), safety data sheet (SDS), dangerous goods declaration, and certificate of origin. EUR.1 movement certificates are available on request for applicable trade routes.

    REACH status is confirmed before we quote. We work with customers on the appropriate importer-of-record arrangements and can advise whether the substance is registered for your intended use. Contact us with your use descriptor and we will confirm compliance.
