2869-83-2 Usage
Description
Janus Green B is a green powder that serves as a vital stain, interacting with DNA and revealing alterations to the electron transfer chain through its oxidation and reduction. It is widely used in various applications due to its staining properties and ability to highlight specific cellular structures.
Uses
Used in Textile Industry:
Janus Green B is used as a dye for cotton and wool, providing vibrant and long-lasting color to these natural fibers.
Used in Biological Staining:
Janus Green B is used as a biological stain for histology studies, particularly for mitochondrial staining. It helps in the effective and rapid staining of insect chordotonal organs and peripheral nerves, where the nerves appear dark blue in comparison to non-stained tissue.
Used in Electrodeposition of Copper:
Janus Green B is utilized in the electrodeposition of copper, as mentioned in the patent by Brown, Fellows, US 2882209 (1959 to Udylite Res. Corp.), which highlights its application in the field of metallurgy and material science.
Used in Lymphatic Vessel Studies:
In rabbit lymphatic vessel studies, Janus Green B has been used to demonstrate that threadlike structures within the lymphatic vessels, known as Bonghan ducts, contain a high density of mitochondria in their cells. This application aids in understanding the cellular composition and function of these structures.
Safety Profile
Poison by
intraperitoneal and intravenous routes.
Moderately toxic by ingestion, skin contact,
subcutaneous, and intramuscular routes.
Human systemic effects by inhalation:
nausea or vomiting. A skin and severe eye
irritant. Flammable liquid when exposed to
heat or flame; can react with oxidizing
materials. To fight fire, use alcohol foam,
CO2, dry chemical. When heated to
decomposition it emits toxic fumes of NOx.

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.
