6153-39-5 Usage
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
Different sources of media describe the Uses of 6153-39-5 differently. You can refer to the following data:
1. Reagent for sugars.
2. Orcinol monohydrate is usually used to prepare colorimetric reagents for the determination of RNA, DNA,and hexoses.
3. 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.
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.]

Check Digit Verification of cas no
The CAS Registry Mumber 6153-39-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,1,5 and 3 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 6153-39:
(6*6)+(5*1)+(4*5)+(3*3)+(2*3)+(1*9)=85
85 % 10 = 5
So 6153-39-5 is a valid CAS Registry Number.

PROCESS FOR STRAIGHTENING KERATIN FIBRES WITH A HEATING MEANS AND DENATURING AGENTS
-
, (2010/03/02)
The invention relates to a process for straightening keratin fibres, comprising: (i) a step in which a straightening composition containing at least two denaturing agents is applied to the keratin fibres, (ii) a step in which the temperature of the keratin fibres is raised, using a heating means, to a temperature of between 110 and 250° C.
