3267-41-2 Usage
Uses
Used in Textile Industry:
5-[(3-Carboxy-2-hydroxy-5-methylphenyl)(3-carboxy-5-methyl-4-oxo-2,5-cyclohexadien-1-ylidene)methyl]-2-hydroxy-3-methylbenzoic acid is used as a dye in the textile industry for its color-changing properties and ability to produce a range of shades. It is also known for its fastness properties, such as ironing fastness, light fastness, fulling, perspiration fastness, soaping, and resistance to water, alkali, and acid, as per the ISO standards.
Used in Other Industries:
While the provided materials do not specify other industries, the unique properties of 5-[(3-Carboxy-2-hydroxy-5-methylphenyl)(3-carboxy-5-methyl-4-oxo-2,5-cyclohexadien-1-ylidene)methyl]-2-hydroxy-3-methylbenzoic acid may also be applicable in other fields, such as cosmetics, pharmaceuticals, or food coloring, due to its color-changing and solubility properties. Further research and development would be required to explore these potential applications.

Check Digit Verification of cas no
The CAS Registry Mumber 3267-41-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,6 and 7 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 3267-41:
(6*3)+(5*2)+(4*6)+(3*7)+(2*4)+(1*1)=82
82 % 10 = 2
So 3267-41-2 is a valid CAS Registry Number.
