Red Phosphorus
Red Phosphorus (Product Code: SCI-430/128) is an analytical reagent grade allotrope of the element phosphorus used to demonstrate allotropy and the combustion of non-metals in school and college chemistry laboratories. It comes as a 50 g pack with an MSDS, and demonstrations typically use only small portions at a time. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, to chemistry departments that source their reagents from one laboratory chemicals supplier in India.

What Is Red Phosphorus Used For?
Red phosphorus lets teachers show allotropy: it is the same element as white phosphorus but far more stable in air, which is why the red form is the one kept in teaching labs and used on the striking strip of safety match boxes. In the combustion-of-non-metals demonstration, a small amount burned on a deflagrating spoon in a gas jar of oxygen produces dense white smoke of phosphorus oxide. Shaken with a little water, the oxide gives an acidic solution that turns blue litmus red.
Red phosphorus is a flammable solid that can ignite through friction, especially when mixed with oxidising agents such as chlorates, so never grind it or store it near oxidisers. Carry out demonstrations in a fume cupboard, keep the container tightly closed in a cool, dry place, and have dry sand ready for smothering a small fire. Some countries control the sale and transport of red phosphorus, so check local regulations before ordering.
Supplier
ScienceLab, the trading name of Jain Scientific Equipments Private Limited, sources Red Phosphorus for teaching laboratories and supplies it with an MSDS. Institutions, dealers and importers in India and international markets should mention the intended use and destination in their enquiry, as flammable solids are subject to transport rules. Company information is on the ScienceLab profile page.

Frequently Asked Questions
What is Red Phosphorus SCI-430/128 used for?
Red Phosphorus SCI-430/128 is used in teacher-led demonstrations of allotropy and of non-metals burning in oxygen to form acidic oxides. Its analytical reagent grade and 50 g pack suit school and college chemistry departments that need small, controlled quantities.
How is red phosphorus different from white phosphorus?
Red Phosphorus is a more stable allotrope than white phosphorus: it does not catch fire spontaneously in air and is far less toxic, so it is the form used in teaching labs. Both consist only of phosphorus atoms, arranged in different structures.
How should Red Phosphorus be stored?
Store Red Phosphorus SCI-430/128 in its tightly closed container in a cool, dry cabinet for flammable solids, away from oxidising agents such as chlorates, nitrates and permanganates. Follow the MSDS supplied with the pack for fire-fighting and spill guidance.
Does Red Phosphorus expire?
The shelf life of Red Phosphorus SCI-430/128 depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted. Keeping moisture out of the container helps the contents stay in good condition.
Are there restrictions on buying Red Phosphorus?
Some countries regulate the sale, transport or export of Red Phosphorus, and flammable solids ship under dangerous-goods rules. Before ordering SCI-430/128, check your local regulations and tell us the destination and intended teaching use so we can advise on supply.
Who supplies Red Phosphorus SCI-430/128?
Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India supplies Red Phosphorus SCI-430/128 with its MSDS to schools, colleges and laboratories, and to dealers and importers in India and international markets, subject to the applicable chemical regulations.
