| Hazard Information | Back Directory | [Description]
A 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 Properties]
White to beige crystalline powder | [Uses]
5-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. | [Uses]
Orcinol monohydrate is usually used to prepare colorimetric reagents for the determination of RNA, DNA,and hexoses.
| [Uses]
Reagent for sugars. | [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 Methods]
Purify 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.] | [References]
