Independent sourcing partner
Propylene Sourcing helps US distributors, formulators and plant buyers record chemical identity, quantity, packaging and destination, then request factory quotations. Polymer-grade propylene (CAS 115-07-1 when that olefin is intended) is not interchangeable with industrial or USP propylene glycol (CAS 57-55-6). This desk does not hold cylinders, claim authorization or treat a family SDS as evidence for a quoted lot.
A first propylene brief is a comparison sheet, not a warehouse check. Similar commercial names can hide different water limits, inhibitor systems or recovered streams, so each step below stays open until a supplier answers against the exact quoted product. Optional budget currency and high-end, mid-range, budget or undecided preference describe a buyer trade-off; they are not ratings this site has verified.
State whether the RFQ is for propylene monomer, polymer-grade olefin, or a glycol grade. Record CAS, intended process and whether polymer, chemical-grade or recovered material is requested.
Write concentration, assay, purity, moisture, density and flash point if you already have them. Mark unknown values for supplier confirmation rather than borrowing a typical technical data sheet.
Choose cylinder, drum, IBC or isotank, then note UN number, labeling and any site unloading limit that can change delivered scope. Transport classification follows the exact SDS.
Ask for current safety data sheet, technical data sheet and certificate of analysis format for the quoted lot. TSCA, REACH or ISO statements belong to that product, not to this desk.

These cells describe buyer starting points inside Basic & Industrial Chemicals. They are not stock lists and do not transfer another catalog’s compliance claims onto your order. Polymerization feedstock, heat-transfer fluid and resin-carrier uses need different concentration, moisture and packaging questions.
Ask whether the quoted propylene is polymer-grade, what residual moisture is controlled, and whether cylinder or pipeline-equivalent package language is even applicable to the destination.
For glycol, ask concentration, inhibitor system, freeze-point statement and whether the quote is USP, industrial or inhibited heat-transfer fluid—not a borrowed family typical.
Record viscosity, water content and residual solvent limits the receiving lab will test. A neighboring grade CoA is not evidence for the lot in hand.
Ask pack-size mix, relabel questions and whether freight, duties and destination charges sit inside or outside the quoted number.
A family safety data sheet is a starting file. Handling, storage and transport decisions wait for the SDS of the exact concentration and package that is quoted.
Ask whether assay, moisture, density, flash point and inhibitor statements are typical values or lot-controlled limits on the technical data sheet.
Request the certificate of analysis fields the receiving lab will accept. A related grade or another producer’s certificate is not evidence for this lot.
Read the buyer procurement brief before sending the form.
A sample can confirm appearance, assay, viscosity or process fit only after you name the method and reviewer. This site does not give mixing or hazardous-use instructions; those stay with qualified EHS and laboratory staff. Final storage and transport follow the exact SDS, UN number and carrier rules.
Optional budget and supplier preference (high-end, mid-range, budget or undecided) describe your trade-off. They are not a verified rating and do not require a current quotation.
