Are Tribromosilane and Silane, tribromo- the same substance?

Yes. Tribromosilane and Silane, tribromo- identify CAS 7789-57-3 and formula HSiBr₃. The shortened expression Silicon Tribromide is imprecise because it omits the bonded hydrogen; purchase documents should use the full name, CAS number, formula and an agreed identity method.

What must be agreed before ordering Tribromosilane?

Confirm assay and method, related bromosilane and hydrolysis impurities, water limit, supplied physical form, quantity, compatible container and valve or closure, inert-gas condition and allowable air or moisture exposure. The receiving site should approve the current SDS, transfer system and emergency controls before shipment.

Tribromosilane CAS 7789-57-3

Tribromosilane, CAS 7789-57-3, is also identified as Silane, tribromo-. Before evaluating a technical or commercial offer, confirm the actual supplied form, assay, water limit, relevant impurity limits, container information and current COA/SDS.

Applications and Grade Selection

Tribromosilane is evaluated for specialized silicon chemistry and controlled synthesis. Grade selection should be based on assay, water, halide impurities, supplied form or concentration and application testing, not on a generic purity, grade or performance claim.

Storage and Packaging

Confirm container compatibility, closure, transport conditions and receiving-site requirements against the current SDS for the exact offered form.

Safety and Documentation

Review the current SDS before handling Tribromosilane. Confirm hazards, PPE, incompatibilities, emergency measures, transport classification and receiving-site controls for the exact supplied form; the product page is not a substitute for lot and shipment documents.
