What is the current price of methanol (CAS 67-56-1)?
ChemExact does not publish public price lists for methanol. No verified supplier has linked this SKU yet — submit an RFQ below and our BD team will return 3+ comparative quotes within 48–72 hours, each with batch traceability and a COA. For background market context only (non-binding), industry bulletins such as ICIS or national commodity indices may be consulted independently.
How has methanol price trended recently?
methanol pricing follows upstream feedstocks, export demand, and plant turnaround cycles. ChemExact does not quote spot indices on this page. For a procurement decision, submit an RFQ — suppliers respond with current lot pricing and lead time. Independent market bulletins (ICIS, national commodity indices) may be used only as non-binding background reference.
Who are the major manufacturers of methanol in China?
China-based manufacturers of methanol (CAS 67-56-1) are matched on demand by the ChemExact business team. Submit an RFQ or contact bd@chemexact.com — a BD advisor will shortlist candidates from regulated directories (e.g. China MEM hazardous-chemicals registration at https://whpdj.mem.gov.cn/) with full provenance on each dossier. Because methanol is listed under China's hazardous-chemicals regime, only licensed entities may produce or trade it. Supplier discovery is handled through ChemExact's verified network, not third-party marketplaces.
Which suppliers in East / North / South China stock methanol?
Regional supply of methanol (CAS 67-56-1) is matched on demand through ChemExact's own verified network. Submit an RFQ stating your target region (East / North / South China), or reach the ChemExact business team at bd@chemexact.com — a BD advisor will match verified producers from regulated enterprise registries and return comparable quotes with COAs. When ChemExact's geo-browse directory is enabled, city-level supplier pages list credentials and last review dates. Cross-province shipment of methanol requires compliant hazmat carriers where applicable.
Who are the largest global producers of methanol?
International supply of methanol (CAS 67-56-1) is arranged by the ChemExact business team based on export credentials. Submit an RFQ or contact bd@chemexact.com — a BD advisor will match qualified exporters and return batch COAs, trade terms, and Incoterms. For regulatory due diligence, consult ECHA REACH (CAS 67-56-1), US EPA CompTox, or Japan NITE — these are compliance references, not procurement marketplaces.
What grades of methanol are commercially available?
methanol is typically supplied in the following grades: Industrial / Technical (≥ 99%, bulk feedstock), Reagent (AR/CP/GR, ≥ 99.5%, lab analytics), HPLC / GC (≥ 99.9%, chromatography & spectroscopy). Grade-specific specs are confirmed via the supplier's SDS and CoA. ChemExact lets verified suppliers attach hash-validated CoA/SDS files on their brand product pages.
Where can I download the SDS / MSDS for methanol (CAS 67-56-1)?
Authoritative SDS sources: ① PubChem 'Safety and Hazards' section — https://pubchem.ncbi.nlm.nih.gov/compound/887; ② US NIH Hazardous Substances Data Bank (HSDB); ③ ECHA REACH dossier; ④ Supplier-attached SDS on verified ChemExact brand pages. ChemExact does not host SDS files directly (to avoid version drift); all SDS links route to source.
