Sodium Nitroprusside Manufacturer,Supplier and Exporter in India

Sodium Nitroprusside (Product Code: SCL-965/225), also known as sodium nitroferricyanide, is an analytical reagent used to detect sulphide ions and ketones by colour tests in chemistry and biochemistry laboratories. Colleges and senior schools use it in salt analysis, the sulphur test on Lassaigne's extract and Legal's and Rothera's ketone tests; the listing gives a 500 ml pack, supplied with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a chemistry consumables supplier in India.

Specifications

What Is Sodium Nitroprusside Used For?

In inorganic qualitative analysis, a few drops of nitroprusside solution added to an alkaline solution or sodium carbonate extract of a salt produce a short-lived violet colour when sulphide is present, which is why the reagent sits in almost every salt analysis kit for school and college practicals. In the organic laboratory the same reaction confirms sulphur in the sodium fusion (Lassaigne's) extract. Because the colour fades within moments, students should watch the tube as the drops go in rather than after shaking.

Biochemistry and life-science teaching labs use the reagent for ketone detection: Legal's test gives a red colour with acetone in alkaline solution, and Rothera's test produces a purple ring with acetone and acetoacetate after saturation with ammonium sulphate and layering with ammonia. Nitroprusside solutions are light-sensitive and slowly lose strength, so keep the container closed in a dark cupboard and run a known positive sample beside each set of unknowns.

Frequently Asked Questions

Who supplies Sodium Nitroprusside SCL-965/225?
Sodium Nitroprusside (SCL-965/225) is supplied by Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, Ambala, Haryana, India. The company sources this analytical reagent, includes its MSDS and supplies colleges, schools and distributors in India and international markets.

What colour shows a positive sulphide test with Sodium Nitroprusside?
A deep violet or purple colour that appears immediately and fades within a short time shows sulphide when Sodium Nitroprusside is added to an alkaline test solution. If no colour appears, confirm the solution is alkaline before concluding that sulphide is absent.

Is the 500 ml Sodium Nitroprusside pack a ready-to-use solution?
The listing gives the Sodium Nitroprusside pack capacity as 500 ml but does not state the physical form or concentration. If you need these confirmed before ordering, please contact us with your intended tests and we will check the current stock for you.

How should Sodium Nitroprusside be stored?
Sodium Nitroprusside should be kept tightly closed, protected from light, in a cool and dry chemical store out of students' reach. It is toxic if swallowed, so handle it with gloves and follow the MSDS supplied with the pack.

What is the shelf life of Sodium Nitroprusside?
Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted. Working solutions of Sodium Nitroprusside are light-sensitive, so replace them whenever a known positive control gives a weak colour.

Can biology departments use Sodium Nitroprusside for ketone tests?
Yes. Sodium Nitroprusside is the key reagent in Legal's and Rothera's tests, which are common teaching experiments for acetone and acetoacetate. These tests are intended for demonstrations; diagnostic laboratories should follow their own validated methods.

Do you supply Sodium Nitroprusside in bulk or for export?
Yes. Multiple packs of Sodium Nitroprusside can be quoted for institutions and distributors in India and international markets. Share the quantity and destination through the contact form so we can confirm packing and shipping for this reagent.
