Acetylsalicylic Acid (Aspirin) – 100g

Acetylsalicylic Acid, widely known as Aspirin, is supplied here in a 100g pack for controlled use in educational laboratory environments. Also referred to as 2‑Acetoxybenzoic Acid or O‑Acetylsalicylic Acid (ASA), this compound is a well‑known organic acid commonly used in chemistry education to support teaching and learning in analytical and organic chemistry.

Identified by CAS number 50‑78‑2, acetylsalicylic acid is frequently used in schools and colleges to demonstrate key chemical concepts such as ester formation, hydrolysis reactions, purification techniques, and melting‑point analysis. Its familiarity and well‑documented properties make it particularly suitable for structured practical work under supervised conditions.

This product is supplied for educational use in line with laboratory best practice. While it is not assigned a UN number (UN: NR), it should still be handled, stored, and disposed of in accordance with COSHH guidance and local school laboratory procedures.
