Product overview & key benefits
Ammonium thiocyanate is a highly soluble salt that supplies the thiocyanate (SCN⁻) ion. It is used as an auxiliary in dyeing, in plating baths and solvent-extraction processes that separate metals, as a reagent in organic synthesis — including pesticide and pharmaceutical intermediates and the separation of antibiotics — and as a classic analytical reagent for iron(III).
The solid is hygroscopic and cakes easily, so moisture matters along with assay, chloride, sulfate and iron.
Soluble SCN⁻ source
Dissolves readily in water and polar solvents for baths, reactions and analytical use.
Limits on the COA
We quote against your assay, chloride, sulfate and iron limits and send the batch COA for each lot.

Selection & comparison
Choosing the right grade
| Your requirement | What usually works |
|---|---|
| Dissolving in batches on site | Solid 98% or 99% |
| Dosing as a liquid | 50% solution |
| Analytical or low-impurity use | 99% solid; specify chloride, sulfate and iron limits |
| Replacing an existing supplier | Send your current TDS or COA; we quote against the parameters you approve |
Packaging & storage
Packaging
Pack size depends on the grade (solid or 50% solution) and is confirmed with the quotation.
Storage
Hygroscopic: keep bags tightly closed in a dry place. Keep away from acids and oxidizers — contact with acids releases very toxic gas. Follow the SDS.
From first email to approved supply
Choose solid or solution
Solid grades suit batch dissolving; the 50% solution saves handling if you dose a liquid.
Compare the numbers that matter
Assay, moisture, chloride, sulfate and iron. Ask for them on the same COA template as your incoming inspection.
Protect from moisture
The solid cakes when it picks up water. Check bags on arrival and reseal opened bags.
Trial, then lock the spec
Run a sample in your own process and keep the approved lot COA as the reference for contract limits.
