12236-29-2 Usage
Description
DisperseYellow39 is a synthetic azo dye characterized by its yellow, red light yellow, and yellow-orange hues. It is commonly used in the dyeing and printing of various synthetic fibers, such as polyester, acetate, triacetate, and polyamide fibers, due to its excellent levelness and good rate of dye uptake.
Uses
Used in Textile Industry:
DisperseYellow39 is used as a dye for polyester, acetate, triacetate, and polyamide fibers to impart vibrant yellow, red light yellow, and yellow-orange shades. It is valued for its levelness and good rate of dye uptake, which ensures even and consistent coloration.
Used in Polyester Dyeing:
DisperseYellow39 is used as a dye for polyester fibers, providing a wide range of yellow shades with excellent light, ironing, perspiration, and washing fastness properties. The ISO ratings for light fastness, ironing fastness, perspiration fastness, and washing fastness are 3-4, 4-5, 7, and 5, respectively.
Used in Acetate and Triacetate Dyeing:
DisperseYellow39 is also used as a dye for acetate and triacetate fibers, offering a similar range of yellow shades with good fastness properties. The ISO ratings for light fastness, ironing fastness, perspiration fastness, and washing fastness are 3-4, 4-5, 5, and 5, respectively.
Used in Polyamide Fiber Dyeing:
DisperseYellow39 is used as a dye for polyamide fibers, delivering a variety of yellow shades with good fastness properties. The ISO ratings for light fastness, ironing fastness, perspiration fastness, and washing fastness are 3-4, 4-5, 5, and 5, respectively.

Check Digit Verification of cas no
The CAS Registry Mumber 12236-29-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,2,3 and 6 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 12236-29:
(7*1)+(6*2)+(5*2)+(4*3)+(3*6)+(2*2)+(1*9)=72
72 % 10 = 2
So 12236-29-2 is a valid CAS Registry Number.

Design, synthesis and investigation of water-soluble hemi-indigo photoswitches for bioapplications
Berdnikova, Daria V.
, p. 2822 - 2829 (2019/12/11)
A series of hemi-indigo derivatives was synthesized and their photoswitching properties in aqueous medium were studied. The dimethoxy hemi-indigo derivative with the best photochromic performance in water was identified as a promising platform for the dev

The potential of azaaurones as dual-stage antimalarial agents was investigated by assessing the effect of a small library of azaaurones on the inhibition of liver and intraerythrocytic lifecycle stages of the malaria parasite. The whole series was screened against the blood stage of a chloroquine-resistant Plasmodium falciparum strain and the liver stage of P. berghei, yielding compounds with dual-stage activity and sub-micromolar potency against erythrocytic parasites. Studies with genetically modified parasites, using a phenotypic assay based on the P. falciparum Dd2-ScDHODH line, which expresses yeast dihydroorotate dehydrogenase (DHODH), showed that one of the azaaurone derivatives has the potential to inhibit the parasite mitochondrial electron-transport chain. The global urgency in finding new therapies for malaria, especially against the underexplored liver stage, associated with chemical tractability of azaaurones, warrants further development of this chemotype. Overall, these results emphasize the azaaurone chemotype as a promising scaffold for dual-stage antimalarials.
