Copper(I) Oxide (Cuprous Oxide) – LR Grade, 250g (UN Approved)

Copper(I) Oxide, also known as Cuprous Oxide, is supplied in a 250g UN‑approved container and manufactured to Laboratory Reagent (LR) grade. This red‑brown inorganic powder is widely used in educational chemistry laboratories due to its clearly defined composition, distinctive colour, and relevance to GCSE and A‑Level inorganic chemistry.

Identified by CAS Number: 1317‑39‑1 and UN Number: 3077, copper(I) oxide is a regulated inorganic substance and must be handled in accordance with appropriate laboratory safety procedures and COSHH risk assessments. It is particularly useful for demonstrating oxidation states of copper, redox chemistry, and the properties of metal oxides under controlled conditions.
