ChemSP — A brand of Jinan Shenghe Chemical Co., Ltd.
High-quality 2-methylene-3-butyn-1-ol supplied by ChemSP Competitive pricing, reliable delivery, and full technical support for B2B buyers worldwide.
ChemSP - your B2B chemical sourcing brand. This product is supplied through our verified manufacturing partner with consolidated logistics and multilingual technical support.
2-methylene-3-butyn-1-ol is offered by ChemSP (Jinan Shenghe Chemical Co., Ltd.) as a catalogued organic chemicals raw material for B2B buyers.
Written as C5H6O, the molecule contains 5 carbon atoms, 6 hydrogen atoms and 1 oxygen atom in a single defined ratio — the basis for assay calculation and for reconciling batch weights against a specification.
At 82.10 it is a low-molecular-weight species, so losses through dusting and evaporation during transfer deserve attention.
| CAS Number | 84100-18-5 |
|---|---|
| Molecular Formula | C5H6O |
| Molecular Weight | 82.10 |
| LogP (calculated) | 0.7 |
| Catalog Category | Organic Chemicals |
The formula points to a hydrocarbon-type framework — worth confirming against structural data before an analytical method is validated.
LogP 0.7 makes it close to balanced between water and octanol, so emulsion or surfactant-assisted handling is usually worth evaluating early.
Typical applications of 2-methylene-3-butyn-1-ol (CAS 84100-18-5; formula C5H6O; 82.10 g/mol) include chemical synthesis, fine chemical manufacturing and related industrial processes. Our sales team answers specification, COA and volume enquiries for 2-methylene-3-butyn-1-ol.
Specific end-uses should be checked against your own regulatory assessment before the material is qualified in a finished product.
Supplied in standard export packaging appropriate to the physical form of the material. The exact pack size, inner liner and net weight are fixed on the order acknowledgement, since they depend on whether the lot ships as a solid, a paste or a liquid. Customers with drum, liner or pallet constraints should specify them when enquiring.
Every lot is released against a written specification and ships with its own COA; the SDS follows the current GHS revision. Where a customer needs an additional test — heavy metals, residual solvent, particle size — it can normally be added to the specification for future lots.
Quotations are issued against the product name and CAS number, with quantity, destination port or address, and any specification adjustments stated in the enquiry. Normal reply time is one business day.
What is the CAS number of 2-methylene-3-butyn-1-ol?
The CAS registry number for 2-methylene-3-butyn-1-ol is 84100-18-5. Please quote it on any enquiry so that a quotation is matched to the correct grade.
Can you supply 2-methylene-3-butyn-1-ol with a specification we define?
Yes. The acceptance criteria can be adjusted within what the route allows — most often assay, moisture, heavy metals or particle size. Any change is written into the specification before the lot is released.
Which documents come with the shipment?
A batch-specific COA and a GHS-format safety data sheet. Additional declarations — non-GMO, allergen, origin, or a customer-specific template — can be issued on request.
2-methylene-3-butyn-1-ol is supplied against a clear, batch-specific specification. When you request a quote, our team confirms the assay or purity grade, physical form, pack size and any residue limits relevant to your application. Typical parameters documented on the Certificate of Analysis include identity (CAS number), molecular formula, molecular weight, appearance, assay, loss on drying and heavy-metal limits where applicable.
Buyers source 2-methylene-3-butyn-1-ol across food and beverage, nutraceutical and pharmaceutical, cosmetic and personal care, and selected industrial formulations. ChemSP aligns the grade and documentation set to the target application and destination market.
ChemSP ships 2-methylene-3-butyn-1-ol with a Certificate of Analysis for every batch and a Safety Data Sheet on request.

The table below is calculated from the molecular formula C5H6O. The values are theoretical and are intended as a reference for incoming inspection and for setting a purchase specification.
At 82.10 g/mol the molar mass is in the small-molecule range, where volatility and dust generation are the practical handling concerns.
Store in a cool, dry, well-ventilated place in the original unopened packaging, away from heat and direct sunlight. Re-test material that has been stored for a long period.
These are the parameters normally reported on a certificate of analysis. Limits are lot-specific and follow the specification agreed between supplier and buyer; no numeric limits are stated or implied here.
2-methylene-3-butyn-1-ol is identified by CAS 84100-18-5, molecular formula C5H6O and a molar mass of 82.10 g/mol.
Calculated from C5H6O, the composition by mass is: C 73.1%, O 19.5%, H 7.4%.
A certificate of analysis normally reports Assay / content, Loss on drying / moisture, Appearance and odour, Heavy metals (as Pb), Shelf life and packaging. Exact limits are agreed with the buyer and are lot-specific.
