Frequently asked questions

Curated by ChemExact's editorial team and reviewed by chemistry and API procurement specialists. Each factual claim is traceable to the cross-source citation graph at the bottom of the page.

What is methyl acetate (CAS 79-20-9)?
methyl acetate is a chemical compound with molecular formula C3H6O2 and molecular weight ≈ 74.08 g/mol. Its CAS Registry Number is 79-20-9. Methyl acetate is an acetate ester resulting from the formal condensation of acetic acid with methanol. A low-boiling (57 C) colourless, flammable liquid, it is used as a solvent for many resins and oils. It has a role as a fragrance, a polar aprotic solvent and an EC 3.4.19.3 (pyroglutamyl-peptidase I) inhibitor. It is a volatile organic compound, a methyl ester and an acetate…
What is the molecular formula and weight of methyl acetate (CAS 79-20-9)?
The molecular formula of methyl acetate is C3H6O2, and the molecular weight is 74.08 g/mol. This data has been cross-verified against PubChem, ChEMBL and CAS Common Chemistry.
What are the SMILES and InChIKey of methyl acetate?
The canonical SMILES of methyl acetate is `CC(=O)OC`, and the InChIKey is `KXKVLQRXCPHEJC-UHFFFAOYSA-N`. These international identifiers are reusable in PubChem, ChemDraw, RDKit and most cheminformatics toolchains.
What are the common synonyms of methyl acetate?

What is the current market price of methyl acetate (CAS 79-20-9)?
ChemExact follows a claimed-supplier real-time pricing model: when a verified supplier claims this product page, the right sidebar shows their public quote, MOQ and validity. Current page status: UNCLAIMED — suppliers welcome to onboard and quote. For market reference, see weekly bulletins from ICIS (icis.com), S&P Global Commodity Insights, or China-side aggregators (Longzhong, Sublime, BAIINFO).
How has methyl acetate price trended recently?
methyl acetate pricing typically tracks upstream feedstocks (oil, propylene/aromatics), export demand and seasonal turnaround schedules. Authoritative trackers include: ① ICIS weekly reports; ② S&P Global Platts; ③ China General Administration of Customs (GACC) export data; ④ China Petroleum & Chemical Industry Federation (CPCIF) monthly bulletins. ChemExact will aggregate public weekly bulletins as a market-reference layer (no quote-binding) in subsequent sprints.
Who are the major manufacturers of methyl acetate in China?
Authoritative public sources for finding licensed Chinese manufacturers of methyl acetate: ① China MEM Hazardous Chemicals Registration System — https://whpdj.mem.gov.cn/ (searchable registered enterprises); ② China Chemical Information Center (CCIN) industry database — http://www.ccin.com.cn/; ③ Public B2B platforms such as Made-in-China.com and Alibaba 1688 (with verified-supplier filters). ChemExact will aggregate the public regulatory lists into a 'potential suppliers' candidate pool (with full provenance) in the next sprint.
Who are the largest global producers of methyl acetate?
Global supply discovery for methyl acetate is best started from public regulatory registries: ① ECHA REACH registered companies — https://echa.europa.eu/information-on-chemicals (by CAS 79-20-9 returns all EU-compliant registrants); ② US EPA CompTox Chemicals Dashboard — https://comptox.epa.gov/dashboard/; ③ Japan NITE Chemical Risk Information Platform (CHRIP). These registries list compliant producers/importers and serve as a credible first-pass shortlist for international procurement.
What grades of methyl acetate are commercially available?
methyl acetate 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 to their claimed product pages.
Where can I download the SDS / MSDS for methyl acetate (CAS 79-20-9)?
Authoritative SDS sources: ① PubChem 'Safety and Hazards' section — https://pubchem.ncbi.nlm.nih.gov/compound/6584; ② US NIH Hazardous Substances Data Bank (HSDB); ③ ECHA REACH dossier; ④ Supplier-attached SDS on the claimed product page. ChemExact does not host SDS files directly (to avoid version drift); all SDS links route to source.
What should be included in a Certificate of Analysis (CoA) for methyl acetate?
A typical industrial CoA for an organic chemical includes: assay (GC%), appearance, density, refractive index, water content (Karl Fischer), acidity, distillation range or boiling point, heavy metals, and iron content. Reagent / pharma grades additionally provide IR / NMR / HPLC traces. ChemExact requires verified suppliers to upload a CoA template upon claiming, so buyers can perform back-validation.
What is the HS code and import procedure for methyl acetate?
Authoritative trade lookups: ① China Customs Tariff (Single Window) — https://www.singlewindow.cn; ② US ITC HTS — https://hts.usitc.gov/; ③ EU TARIC — https://taric.ec.europa.eu/. ChemExact will integrate GACC's public HS code dataset in Sprint 4.
