Orcinol monohydrate Usage And Synthesis
  • DescriptionA pyranoquinolone alkaloid found in Oricia suaveolens, this base does not form salts with mineral acids. The structure has been established by synthesis as 6:7- dimethoxy-N-methylflindersine.
  • Chemical PropertiesWhite to beige crystalline powder
  • UsesReagent for sugars.
  • UsesOrcinol monohydrate is usually used to prepare colorimetric reagents for the determination of RNA, DNA,and hexoses.
  • Uses5-Methylbenzene-1,3-diol Hydrate is the hydrated form of 3,5-Dihydroxytoluene(D454760); 3,5-Dihydroxytoluene is found in lichen fungi and can improve functional properties of lysozyme.
  • General Description
    Orcinol is a small-molecule natural phenol involved in the production of a dye called orcein used for the staining of cells and chromosomes. Orcinol monohydrate is usually used to prepare a colorimetric reagent known as Bial′s reagent for the determination of RNA, DNA, and hexoses.
  • Purification MethodsPurify orcine by recrystallisation from H2O as the monohydrate. It sublimes in vacuo, and the anhydrous compound has m 106.5-108o (110o, 108o). It can be recrystallised from CHCl3 (plates) or *C6H6 (needles or prisms). [UV: Kiss et al. Bull Soc Chim Fr 275 1949, Adams et al. J Am Chem Soc 62 732 1940.]
