Styrene (Stabilised) – LR Grade, 250ml (UN Approved)

Styrene (Stabilised), also known as Phenylethene monomer, is supplied in a 250ml UN‑approved container and produced to Laboratory Reagent (LR) grade. The stabilised formulation helps prevent premature polymerisation, making it suitable for controlled use in educational chemistry laboratories.

Identified by CAS Number: 100‑42‑5 and UN Number: 2055, styrene is a flammable organic liquid and must be handled in accordance with laboratory safety procedures and COSHH risk assessments. It is widely used in teaching to demonstrate the chemistry of alkenes, aromatic compounds, and polymer formation.

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 option to appear. Orders are shipped only to school addresses in line with safety and regulatory requirements.

Due to courier and safety regulations, chemical products cannot be returned. This does not affect statutory rights.
