2869-83-2 Usage
Chemical Properties
green powder
Uses
Different sources of media describe the Uses of 2869-83-2 differently. You can refer to the following data:
1. As dye for cotton, wool; as biological stain; in electrodeposition of copper, Brown, Fellows, US 2882209 (1959 to Udylite Res. Corp.).
2. Janus Green B is a stain that interacts with DNA and has been used for histology studies including mitochondrial staining, in which its oxidation and reduction reveals alterations to the electron transfer chain. The stain has been utilized in studies for effective and rapid staining of insect chordotonal organs and peripheral nerves, where the nerves appear dark blue in comparison to non stained tissue. With the use of Janus Green B, rabbit lymphatic vessel studies demonstrate that threadlike structures within the lymphatic vessels, known as Bonghan ducts, contain a high density of mitochondria in their cells.
Safety Profile
Poison by

Purification Methods
The dye dissolves in H2O to give a bluish violet solution which becomes colourless when made 10M in NaOH. It dissolves in EtOH to give a blue-violet colour, filter from insoluble material, then add dry Et2O whereby the dye separates out leaving a small amount of blue colour in solution. Filter off the solid and dry it in a vacuum. Store it in a dark bottle. [Colour Index Vol 4, 3rd edn, 4015 1971.]
Check Digit Verification of cas no
The CAS Registry Mumber 2869-83-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,6 and 9 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 2869-83:
(6*2)+(5*8)+(4*6)+(3*9)+(2*8)+(1*3)=122
122 % 10 = 2
So 2869-83-2 is a valid CAS Registry Number.
