632-68-8 Usage
Description
ROSE BENGAL is a synthetic dye that exhibits unique properties and characteristics, making it suitable for various applications across different industries. It is known for its bright blue light pink color and its solubility in water, which results in a blu-ray red hue without fluorescence. When exposed to strong sulfuric acid, ROSE BENGAL turns brown, and upon dilution, it forms a pink precipitate.
Uses
Used in Textile Industry:
ROSE BENGAL is used as a dye for coloring fabrics. Its ability to produce a bright blue light pink color makes it a popular choice for creating vibrant and visually appealing textiles.
Used in Photography Industry:
ROSE BENGAL is used as a photographic sensitizer due to its unique light-sensitive properties. It enhances the sensitivity of photographic film or paper to specific wavelengths of light, allowing for better image capture and reproduction.
Used in Analytical Chemistry:
ROSE BENGAL is used as an analytical reagent for the detection and quantification of various substances, such as proteins, nucleic acids, and other biomolecules. Its ability to bind to these molecules and produce a color change makes it a valuable tool in research and quality control.
Used in Biotechnology:
ROSE BENGAL is used as a stain in biotechnology for the visualization of cellular structures and components. Its ability to bind to specific cellular components and produce a color change allows for the easy identification and analysis of these structures.
Standard:
ROSE BENGAL has been tested and standardized for various properties, including light fastness, soaping, perspiration fastness, oxygen bleaching, and fastness to seawater. The ISO and AATCC ratings indicate the performance of ROSE BENGAL in these areas, with higher numbers representing better performance. For example, ROSE BENGAL has an ISO rating of 1 for light fastness and 4 for soaping, while it has an AATCC rating of 1 for fading and 3-4 for stain resistance.

Check Digit Verification of cas no
The CAS Registry Mumber 632-68-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,3 and 2 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 632-68:
(5*6)+(4*3)+(3*2)+(2*6)+(1*8)=68
68 % 10 = 8
So 632-68-8 is a valid CAS Registry Number.
