Cinnamic Acid (Phenylacrylic Acid) – LR Grade, 100 g

Cinnamic Acid, also known as Phenylacrylic Acid, is supplied in a 100 g pack and manufactured to Laboratory Reagent (LR) grade. This aromatic organic acid is widely used in educational chemistry laboratories for the study of aromatic compounds, unsaturated acids, and structure–reactivity relationships.

Identified by CAS Number: 140‑10‑3 and with no UN number, cinnamic acid is not classified as hazardous for transport when handled appropriately. It is a white to faintly yellow crystalline solid with limited solubility in water and greater solubility in organic solvents, making it suitable for purification, recrystallisation, and organic synthesis demonstrations.

Supplied in solid form for ease of weighing and storage, this reagent provides reliable and repeatable results for supervised laboratory investigations.
