Description
Disperse Black 9 is a brown-black powder that is a type of disperse dye used for coloring synthetic fibers such as polyester, nylon, and acrylic.
Uses
Used in Textile Industry:
Disperse Black 9 is used as a dye for coloring synthetic fibers in the textile industry. It provides excellent colorfastness properties, including ironing fastness, light fastness, perspiration fastness, and washing fastness. According to ISO standards, it has a rating of 2-3 for staining and 4 for fading in standard (polyamide) conditions. In light fastness, it has a rating of 4, and in perspiration and washing fastness, it has a rating of 4-5. According to AATCC standards, it has a rating of 3-4 for staining and 4-5 for fading in standard conditions.
Used in Plastics Industry:
Disperse Black 9 can also be used as a colorant for coloring plastics, providing good dispersion and color stability.
Used in Printing Industry:
In the printing industry, Disperse Black 9 can be used as an ink additive to provide a deep black color with good light fastness and resistance to fading.

Check Digit Verification of cas no
The CAS Registry Mumber 12222-69-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,2,2 and 2 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 12222-69:
(7*1)+(6*2)+(5*2)+(4*2)+(3*2)+(2*6)+(1*9)=64
64 % 10 = 4
So 12222-69-4 is a valid CAS Registry Number.

The development of photometric sensors for boronic acids
Springsteen, Greg,Ballard, C. Eric,Gao, Shouhai,Wang, Wei,Wang, Binghe
, p. 259 - 270 (2001)
Boronic acids bind certain 1,2- and 1,3-diols with high affinity through reversible formation of boronate esters. They have been utilized as the recognition moiety for artificial receptors, particularly receptors for carbohydrates that have cis-diol moieties. Therefore, sensors for boronic acids could serve as universal reporters for monitoring boronate formation. This paper reports the design and synthesis of a series of photometric chemosensors for phenylboronic acid using diethanolamine as the recognition moiety. Diethanolamine, which binds strongly to boronic acids, has been linked to three different types of optical reporters. A photoinduced electron transfer system based on the anthracene fluorophore has been used to create sensors that show up to a fivefold increase in fluorescent intensity in the presence of millimolar concentrations of phenylboronic acid. Sensor designs based on the restriction of free rotation of extended π systems and on the perturbed electronic properties of azo dyes are also included. This work demonstrates that sensors based on several different designs can be used for the detection of boronic acids.
