4439-05-8 Usage
General Description
Basic fuchsin leuconitrile is a synthetic dye that is commonly used in histology for staining biological samples. It is a cationic dye that binds to negatively charged components of cells, such as nucleic acids and proteins, allowing for visualization under a microscope. Basic fuchsin leuconitrile is commonly used in the Gram stain technique to differentiate between Gram-positive and Gram-negative bacteria based on their cell wall compositions. Additionally, it is used in the Ziehl-Neelsen stain for the detection of acid-fast bacteria, such as Mycobacterium tuberculosis. The dye has a vibrant red color and is highly soluble in water, making it an effective and versatile tool in the field of histology and microbiology.
Check Digit Verification of cas no
The CAS Registry Mumber 4439-05-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,3 and 9 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4439-05:
(6*4)+(5*4)+(4*3)+(3*9)+(2*0)+(1*5)=88
88 % 10 = 8
So 4439-05-8 is a valid CAS Registry Number.

Photochemistry and photophysics of triarylmethane dye leuconitriles
Jarikov,Neckers
, p. 659 - 671 (2007/10/03)
The photochemical reactions of crystal violet leuconitrile (CVCN) were investigated by the means of product analysis and trapping experiments, laser flash and steady-state photolysis, and steady-state fluorescence. The influence of oxygen on the reaction was examined in detail. The photochemistry of malachite green leuconitrile (MGCN), basic fuchsin leuconitrile (BFCN), and crystal violet leucomethyl (CVMe) and leucobenzyl (CVBn), as well as triphenylacetonitrile, was studied. The results suggest ionization occurs from S1, while the di-π-methane reaction is the photochemical route from T1.
