General description

Purpurin is a synthetic photosensitizer. It has tissue-penetrating property as its major absorption peak is between 650-715 nm. It is widely used as anthraquinone pigment in food colouring, textile industry, paint industry and medicinal treatments.

Application

Traditionally it has been used to dye cotton fabric materials. It may be used as reference standard in identifying red natural dyes using High performance liquid chromatography (HPLC) with UV-Vis Diode Array Detection (DAD) and electrospray mass spectrometric (ESI-MS) method.

Other Notes

Complexing agent for the spectrophotometric detm. of metals, e.g. La and Pb
