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 acetic acid (CAS 64-19-7)?
acetic acid is a chemical compound with molecular formula C2H4O2 and molecular weight ≈ 60.05 g/mol. Its CAS Registry Number is 64-19-7. Acetic acid is a simple monocarboxylic acid containing two carbons. It has a role as a protic solvent, a food acidity regulator, an antimicrobial food preservative and a Daphnia magna metabolite. It is a conjugate acid of an acetate.
What is the molecular formula and weight of acetic acid (CAS 64-19-7)?
The molecular formula of acetic acid is C2H4O2, and the molecular weight is 60.05 g/mol. This data has been cross-verified against PubChem, ChEMBL and CAS Common Chemistry.
What are the SMILES and InChIKey of acetic acid?
The canonical SMILES of acetic acid is `CC(=O)O`, and the InChIKey is `QTBSBXVTEAMEQO-UHFFFAOYSA-N`. These international identifiers are reusable in PubChem, ChemDraw, RDKit and most cheminformatics toolchains.
What are the common synonyms of acetic acid?
Common synonyms of acetic acid include: acetic acid, 64-19-7, ethanoic acid, Acetic acid glacial, Ethylic acid, Vinegar acid, Glacial acetic acid, Acetic acid, glacial — 20 synonyms in total. The full list (sourced from PubChem) is available in the page header under "Show synonyms".
What is the current market price of acetic acid (CAS 64-19-7)?
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 acetic acid price trended recently?
acetic acid 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 acetic acid in China?
Authoritative public sources for finding licensed Chinese manufacturers of acetic acid: 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). Note: acetic acid is on China's Hazardous Chemicals Catalogue, so all production/trading entities must hold the corresponding operating licenses. 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 acetic acid?
Global supply discovery for acetic acid is best started from public regulatory registries: ① ECHA REACH registered companies — https://echa.europa.eu/information-on-chemicals (by CAS 64-19-7 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 acetic acid are commercially available?
acetic acid 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), and where applicable a pharmaceutical grade meeting USP/EP/JP. 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 acetic acid (CAS 64-19-7)?
Authoritative SDS sources: ① PubChem 'Safety and Hazards' section — https://pubchem.ncbi.nlm.nih.gov/compound/176; 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 acetic acid?
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 licenses are required to procure or transport acetic acid?
Because acetic acid is listed under 应急管理部危险化学品目录, the following licenses apply under China's *Regulations on the Safe Management of Hazardous Chemicals*: ① distributors must hold a Hazardous Chemicals Business License; ② end-users handling highly toxic / explosive precursors require a Use License; ③ road transport must be performed by carriers holding Hazardous Goods Road Transport qualifications, using purpose-built vehicles and certified attendants; ④ cross-border shipment must additionally comply with IMDG (sea), IATA (air), or ADR (road) rules. Refer to the latest MEM rulings.
