Fluorescein is a synthetic organic compound that appears as a dark orange/red powder and is slightly soluble in water and alcohol. It is widely used as a fluorescent tracer for many applications.
Fluorescein is a fluorescent group commonly used in microscopes, dye lasers as gain media, forensic and serological detection of potential blood stains, and dye tracing. The maximum absorption wavelength of fluorescein is 494 nm, and the maximum emission wavelength is 521 nm (in water). The main derivatives are fluorescein isothiocyanate (FITC) and 6-FAM phosphorous amide in oligonucleotide synthesis.

Pigment blue 29, also known as ultramarine blue, is a multi-component inorganic pigment (sulfur-containing sodium aluminosilicate), also known as cloud blue or ocean blue. Ultramarine is insoluble in water and is resistant to alkali, weather resistance and light resistance. However, it changes color when exposed to acid and has weak tinting and hiding power. Pigment blue 29 has a wide range of uses and is commonly used in coatings, plastics, resins, inks, construction, paper, detergents, painting pigments, cosmetics and other industries.
