Product Description

Property

CAS No.: 1562-94-3 Formula: C14H14N2O3 Molecular Weight: 258.27300

Description

para-Azoxyanisole (PAA) is an organic, aromatic compound. In a solid state, it appears as a white powder, but when heated it forms a liquid crystal. As one of the first known and most readily prepared liquid crystals, PAA has played an important role in the development of liquid crystal displays.
Its liquid crystal range is from 118°C to 136°C. The solid to nematic transition is at 118°C and the nematic to isotropic liquid transition at 136°C.
