Product Overview
Polysiloxanes di-Me hydrogen-terminated is a Specialty Chemicals product supplied by ChemSP, the ingredient brand of Jinan Shenghe Chemical Co., Ltd.
The molecular formula C6H20O2Si3 resolves to 6 carbon atoms, 20 hydrogen atoms, 2 oxygen atoms and 3 silicon atoms per molecule, which fixes both the stoichiometry and the equivalent weight used in every downstream calculation.
With MW 208.48 the material is a small molecule in the usual fine-chemical range, handled much like other solid or liquid intermediates of similar size.

Composition and Key Properties
From the composition alone the material presents an oxygenated aliphatic or aromatic skeleton (alcohol, ether, ester or acid functionality), which dictates the compatible solvent set. The hydrogen-to-carbon ratio above two suggests a saturated, open-chain structure rather than an aromatic ring system.
Applications and Use Cases
Polysiloxanes di-Me hydrogen-terminated (CAS 1189-93-1, molecular formula C6H20O2Si3, molecular weight 208.48 g/mol) is mainly applied in chemical synthesis, fine chemical manufacturing and related industrial processes. For specification, COA and bulk prices of Polysiloxanes di-Me hydrogen-terminated, write to our sales team.
- Pilot evaluation before volume commitment.
- Use where a defined performance effect is required and the commodity grade will not deliver it.
- Custom formulation work with a specification agreed against the end use.
Specific end-uses should be checked against your own regulatory assessment before the material is qualified in a finished product.
Packaging and Handling
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.
Quality and Documentation
Documentation released with the lot includes a batch-specific COA, a GHS-format safety data sheet, and a specification sheet reflecting the agreed acceptance criteria. Retained samples are kept so that a later query can be checked against the original material.
Supply and Quotation
Pricing depends on quantity and destination, so a short enquiry — product, CAS, quantity, delivery point — is enough for us to respond with a firm offer, normally the next business day.
Frequently Asked Questions
What is the CAS number of Polysiloxanes di-Me hydrogen-terminated?
The CAS registry number for Polysiloxanes di-Me hydrogen-terminated is 1189-93-1. Please quote it on any enquiry so that a quotation is matched to the correct grade.
Is Polysiloxanes di-Me hydrogen-terminated a stock item or made to order?
Availability moves with the production schedule, so it is confirmed at the time of enquiry. For repeat volumes a scheduled call-off arrangement is usually preferable to one-off orders.
Can you supply Polysiloxanes di-Me hydrogen-terminated 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.

Extended Specifications
Polysiloxanes di-Me hydrogen-terminated 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.
Applications by Industry
Buyers source Polysiloxanes di-Me hydrogen-terminated 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.
Regulatory & Compliance Support
ChemSP ships Polysiloxanes di-Me hydrogen-terminated with a Certificate of Analysis for every batch and a Safety Data Sheet on request. Additional documentation such as specification sheets, third-party test reports and regulatory support letters is available to qualified buyers to streamline import, registration and quality-assurance workflows.
Storage & Handling
Store Polysiloxanes di-Me hydrogen-terminated in a cool, dry, well-ventilated area in its original, tightly closed container, protected from moisture and direct sunlight. Follow the precautions in the Safety Data Sheet and standard chemical-handling guidance. Shelf life and re-test intervals are stated on the Certificate of Analysis.
Frequently Asked Questions
What is the minimum order quantity (MOQ)?
MOQ depends on grade and pack size. Sampling quantities typically start from 1 kg, with commercial volumes from 25 kg. Share your required volume and we will quote accordingly.
Can I request a sample and a Certificate of Analysis?
Yes. Samples and batch-specific Certificates of Analysis are available on request, and third-party testing can be arranged for qualified buyers.
What documentation supports import and registration?
Every shipment includes a Certificate of Analysis. The Safety Data Sheet, specification sheets and regulatory support letters are provided on request to support customs clearance and product registration in your market.
What are the typical lead times and payment terms?
Lead times vary with grade and volume. ChemSP quotes a firm delivery window with each offer, and standard international trading terms apply.
