Sulfocianur Ammonium (Product Code: SCI-731/321), also known as ammonium thiocyanate or ammonium sulfocyanide, is an analytical reagent grade salt used to detect iron(III) ions and to demonstrate endothermic processes in school and college chemistry laboratories. It comes as a 100 g pack with its MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, which stocks it as a lab chemicals supplier in India and for international buyers.

Its best-known use is the thiocyanate test for iron(III): a few drops of the solution turn any liquid containing iron(III) ions blood-red, sensitive enough to reveal traces of iron in water samples or dissolved rust. Iron(II) gives no strong colour until it is oxidised, so the same test helps students tell the two oxidation states of iron apart.
Ammonium thiocyanate dissolves in water with a noticeable fall in temperature, and when the dry salt is mixed with solid barium hydroxide octahydrate the reaction absorbs so much heat that a wet beaker can freeze to a wooden board — a memorable endothermic demonstration for the teacher to run in a ventilated room, because ammonia is released. In analytical chemistry it is also the titrant in Volhard's method for silver, with an iron(III) salt as the indicator.
Jain Scientific Equipments Private Limited, which trades as ScienceLab, supplies Sulfocianur Ammonium from Ambala in 100 g packs with the MSDS to schools, colleges and analytical laboratories. Institutional buyers who need vendor registration details can use the company's CIN U29309HR2020PTC087597 and GSTIN 06AAECJ8618A1ZT. Thiocyanate salts, iron salts and glassware for the same practical can go on one quotation for institutions, dealers and importers in India and international markets, and the ScienceLab profile gives more background.

Is Sulfocianur Ammonium the same as ammonium thiocyanate?
Yes. Sulfocianur Ammonium SCI-731/321 is ammonium thiocyanate, also called ammonium sulfocyanide in older texts. It is supplied as a 100 g analytical reagent pack with its MSDS for iron(III) tests, endothermic demonstrations and thiocyanate titrations.
How is Sulfocianur Ammonium used to test for iron(III)?
Dissolve a little Sulfocianur Ammonium in water and add a few drops to the test solution: a blood-red colour shows iron(III) ions. Iron(II) gives no strong colour until it is oxidised, so the test also distinguishes the two oxidation states of iron.
Why does Sulfocianur Ammonium get cold when dissolved?
Dissolving Sulfocianur Ammonium in water absorbs heat from the surroundings, so the solution becomes noticeably cold. The effect is far stronger when the dry salt reacts with solid barium hydroxide octahydrate, a classic endothermic demonstration done in a ventilated room because ammonia is released.
How should Sulfocianur Ammonium be stored?
Keep Sulfocianur Ammonium SCI-731/321 tightly closed in a cool, dry place, because the salt absorbs moisture, and away from acids and oxidising agents. Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted.
Who supplies Sulfocianur Ammonium SCI-731/321?
Sulfocianur Ammonium SCI-731/321 is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India. The company sources the reagent and provides it with its MSDS to schools, colleges, analytical laboratories, dealers and importers in India and international markets.
What does a Sulfocianur Ammonium quotation need?
A Sulfocianur Ammonium quotation needs the product code SCI-731/321, the number of 100 g packs, your delivery location and any iron salts or glassware for the same practical. Send the list through the contact page or the enquiry cart for a reply.
Request Sulfocianur Ammonium through the ScienceLab contact page or the enquiry cart, and mention whether you also need an iron(III) salt for the red colour test.
