NUCLEAR FAST RED Usage And Synthesis

Chemical Properties

crystalline powder

Definition

ChEBI: An organic sodium salt that is the monosodium salt of 4-amino-1,3-dihydroxy-9,10-dioxo-9,10-dihydroanthracene-2-sulfonic acid. It forms bright red lakes with calcium and is a useful red nuclear staining lake with aluminum.

Purification Methods

A solution of 5g of the dye in 250mL of warm 50% EtOH is cooled to 15o for 36hours, then filtered on a Büchner funnel, washed with EtOH until the washings are colourless, then with 100mL of Et2O and dry it over P2O5 in vacuo. It is a biological stain which is also used for the estimation of Ca.
