What is the current market price of sodium 2-dodecoxyethyl sulfate (CAS 9004-82-4)?
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 sodium 2-dodecoxyethyl sulfate price trended recently?
sodium 2-dodecoxyethyl sulfate 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 sodium 2-dodecoxyethyl sulfate in China?
Authoritative public sources for finding licensed Chinese manufacturers of sodium 2-dodecoxyethyl sulfate: 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 sodium 2-dodecoxyethyl sulfate?
Global supply discovery for sodium 2-dodecoxyethyl sulfate is best started from public regulatory registries: ① ECHA REACH registered companies — https://echa.europa.eu/information-on-chemicals (by CAS 9004-82-4 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 sodium 2-dodecoxyethyl sulfate are commercially available?
sodium 2-dodecoxyethyl sulfate 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 sodium 2-dodecoxyethyl sulfate (CAS 9004-82-4)?
Authoritative SDS sources: ① PubChem 'Safety and Hazards' section — https://pubchem.ncbi.nlm.nih.gov/compound/23665884; 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 sodium 2-dodecoxyethyl sulfate?
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.
