Copper(I) Oxide (Cuprous Oxide) – LR Grade, 100g (UN Approved)

Copper(I) Oxide, also known as Cuprous Oxide, is supplied in a 100g 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 and distinctive physical appearance.

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.

Please note: this chemical is supplied exclusively to educational establishments. Customers must be logged in with an approved school or institutional account for the Add To Basket button to appear. Orders are shipped only to school addresses. Due to courier regulations, chemical products cannot be returned; statutory rights remain unaffected.
