2390-54-7 Usage
Uses
Used in Textile Industry:
Thioflavin T is used as a dye in textile dyeing, particularly for creating brilliant green shades when combined with green or blue pigments.
Used in Signage and Paint Industry:
Thioflavin T serves as a fluorescent sign paint, adding a vibrant green light yellow color to various applications.
Used in Neurology and Research:
Thioflavin T is utilized as a staining agent to visualize beta-amyloid plaques, which are associated with Alzheimer's Disease. This aids in the study and diagnosis of the condition.
Properties and Applications:
Thioflavin T is soluble in cold water, turning yellow, and becomes easily soluble in hot water, also resulting in a yellow color. It exhibits green fluorescence and, when treated with strong sulfuric acid, turns colorless but still fluoresces green. When diluted, it appears light yellow.
Standard (Silk):
Thioflavin T has been tested for its performance on silk, with the following ratings for various fastness properties:
Light Fastness: C (3)
Perspiration Fastness: 2-3
Ironing Fastness: 4
Soaping: 1
Fading: Stain
Stain: Fading
These ratings indicate the dye's performance and stability under various conditions, making it a valuable tool in the textile and research industries.

Check Digit Verification of cas no
The CAS Registry Mumber 2390-54-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,3,9 and 0 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 2390-54:
(6*2)+(5*3)+(4*9)+(3*0)+(2*5)+(1*4)=77
77 % 10 = 7
So 2390-54-7 is a valid CAS Registry Number.

Phototoxic insecticidal composition and method for controlling insect populations
-
, (2008/06/13)
A phototoxic insecticidal composition includes at least one photoactive dye present in the amount of between 0.025%-4.0% of the composition, an attractant compound and/or feeding stimulant and at least one adjuvant, whereby the adjuvant interacts with the photoactive dye and insect membranes to alter the toxicity of the composition once ingested by the insect.
