Fluorescein (lactone form) is a xanthene dye that is highly fluorescent, detectable even when present in minute quantities. Used forensically to detect traces of blood, in analytical chemistry as an indicator in silver nitrate titrations and in microscopy. It has a role as a radioopaque medium and a fluorescent dye. It is a polyphenol, a gamma-lactone, a xanthene dye, an oxaspiro compound, an organic heteropentacyclic compound and a member of 2-benzofurans. It is functionally related to a fluorescein (acid form).

측정된 물성

성상: Fluorescein appears as yellow amorphous solid or orange-red crystals. Latter have greenish-yellow fluorescence by reflected light. Insoluble in water. Soluble in dilute aqueous bases. Very dilute alkaline solutions exhibit intense, greenish-yellow fluorescence by reflected light. Low toxicity. May be sensitive to prolonged exposure to light. · Yellowish-red to red solid, [Merck Index] Orange powder, [MSDSonline]
