How rhenium tetrachloride fits Industrial Chemicals: how to use, pair and avoid the traps
Every time someone asks if our rhenium tetrachloride (CAS 13569-71-6) spec is acceptable, I don't say yes or no immediately. I look at your Industrial Chemicals scene first, then back into the indicators to check. This page spells that out.

Figures above are published / typical information; final values follow the batch COA and order confirmation.
Key physical data: molecular formula Cl4Re, molecular weight 328.0 g/mol, CAS 13569-71-6. Sourced from public chemical databases such as PubChem, ChemSpider and the CAS Registry; the CAS number is the authoritative registry identifier. Purity and packaging follow the batch COA and order confirmation.
Starting with the mechanism
This is the part that's most counter-intuitive:Industrially, the value of rhenium tetrachloride (CAS 13569-71-6) is rarely on the spec sheet — it is whether it stably meets your process window. In Industrial Chemicals, its purity, impurity profile and batch consistency usually matter more than a single 'assay' number, because what really moves the finished result is often the ignored impurities and physical properties. Comparable grades:
- Ammonium bromide (CAS 12124-97-9)：a comparable grade often evaluated alongside。
- Aluminium stearate (CAS 637-12-7)：a comparable grade often evaluated alongside。
- Acetic acid,sodium salt trihydrate (CAS 6131-90-4)：a comparable grade often evaluated alongside。
- Albuterol sulfate (CAS 51022-70-9)：a comparable grade often evaluated alongside。
- Ammonium thiosulfate (CAS 7783-18-8)：a comparable grade often evaluated alongside。
- Aluminium Oxide (CAS 1344-28-1)：a comparable grade often evaluated alongside。
- atropine sulphate (CAS 55-48-1)：a comparable grade often evaluated alongside。
- Adenosine 5'-triphosphate, disodium salt (CAS 987-65-5)：a comparable grade often evaluated alongside。
Checks worth running before you order
- Most practically, the top item is: Define the end use and process window first, then work back to required purity and impurity limits — not the other way around.
- Check compatibility with other materials in the system; run a trial when unsure.
- Match packaging and feeding method to on-site equipment so the material is usable on arrival.
- Retain samples of critical lots and run third-party checks; do not rely on the supplier COA alone.
The easiest things to miss
Comparing price but not impurity profile: same assay with different impurities can yield wildly different results.
Skipping samples and scaling up: going straight to volume most often fails on compatibility.
Ignoring transport and storage: most 'arrived-dead' cases trace back to loose handling.
Things we get asked a lot
In a COA for rhenium tetrachloride, which values best reveal batch stability?
Residual solvent, colour, moisture and heavy metals carry more signal than the assay line; different suppliers use different COA templates, so pick the 2-3 limits that matter for your use and compare those across vendors.
Between bench and scale-up, where does rhenium tetrachloride most often fail?
The dosing point and contact time — at scale, heat/mass transfer degrade, and compatibility issues that didn't show at the bench surface here; run 2-3 graded trials before going to full volume.
How do I match rhenium tetrachloride packaging to my site?
Work backward from dosing frequency and metering precision: continuous dosing suits bags/drums, intermittent suits smaller packs; and the pack material (PE/PP/glass) must be compatible with the material to avoid uptake or migration.
What is the molecular formula and weight of rhenium tetrachloride?
For rhenium tetrachloride, the molecular formula is Cl4Re and molecular weight about 328.0 g/mol (CAS 13569-71-6). These are published physical properties; exact purity, specification and packaging follow the batch COA and order confirmation.
