3564-18-9 Usage
Description
Mordant Blue 3, also known as Chromoxane Cyanine R, is an organic sodium salt that serves as a dye for metal detection. It is the trisodium salt of 5-[(3-carboxy-5-methyl-4-oxocyclohexa-2,5-dien-1-ylidene)(2-sulfophenyl)methyl]-2-hydroxy-3-methylbenzoic acid. Mordant Blue 3 is characterized by its reddish-blue powder form and has the ability to dissolve in various solvents, displaying different colors depending on the solvent used.
Uses
Used in Metal Detection:
Mordant Blue 3 is used as a dye for the detection of some metals in tissue. Its ability to interact with metals makes it a valuable tool in various applications, such as identifying and analyzing metal presence in biological samples.
Used in Textile Industry:
Mordant Blue 3 is used as a dye in the textile industry for coloring fabrics. Its solubility in water and ethanol allows it to produce different shades of red and orange, depending on the solvent used. The dye is known for its fastness properties, which include:
Ironing Fastness: ISO 5, AATCC 4
Light Fastness: ISO 6, AATCC 4
Perspiration Fastness: ISO 5, AATCC 5
Soaping: ISO 5, AATCC 5
Water: ISO 5, AATCC 5
Alkali: ISO 5
Acid: ISO 5
These fastness properties ensure that the dye maintains its color and quality even under various conditions, making it a reliable choice for textile applications.

Check Digit Verification of cas no
The CAS Registry Mumber 3564-18-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,5,6 and 4 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 3564-18:
(6*3)+(5*5)+(4*6)+(3*4)+(2*1)+(1*8)=89
89 % 10 = 9
So 3564-18-9 is a valid CAS Registry Number.
