Tetrazolium Salt (Pure) – LR Grade, 5g

Tetrazolium Salt, chemically known as 2,3,5‑Triphenyltetrazolium Chloride (TTC), is a specialised Laboratory Reagent (LR) grade chemical supplied in a 5g pack. This compound is widely used in biological and biochemical investigations and is particularly valuable in educational laboratories for demonstrating metabolic activity in living tissues.

The product has a CAS Number of 298‑96‑4 and no UN number assigned (UN: NR). Tetrazolium salts are typically supplied as a fine powder that forms coloured products when reduced, making them ideal for visual experiments and investigative practical work in school science settings.

Supplied clearly labelled for traceability and safe handling, this reagent is suitable for controlled laboratory use when standard school safety procedures are followed.

Ideal for School Science Lessons

Tetrazolium salt is especially useful in GCSE and A Level biology and advanced chemistry lessons, where it supports investigations into living systems and enzyme activity. Its visual colour change makes it particularly engaging for students and effective for reinforcing theoretical concepts.

• Demonstrating respiration and metabolic activity in living cells or seeds
• Investigating enzyme‑catalysed reactions
• Supporting practical work on cell viability
• Enhancing understanding of redox reactions
• Developing practical skills in controlled biological testing

When used under appropriate supervision, Tetrazolium Salt provides an excellent opportunity for students to explore biological processes through hands‑on investigation, helping to deepen understanding and build confidence in practical science skills.
