Used in Building Materials:
HALS 292 is used as a UV stabilizer in building materials to provide long-term protection against the harmful effects of UV light. This helps maintain the structural integrity and appearance of the materials, ensuring their durability and longevity.
Used in Agricultural Films:
HALS 292 is used as a UV stabilizer in agricultural films to protect them from degradation and discoloration caused by exposure to sunlight. This helps maintain the effectiveness and longevity of the films, ensuring their ability to protect crops and promote growth.
Used for Thermal Stability and Processing Benefits:
HALS 292 provides thermal stability and processing benefits in various industries, making it a versatile and valuable additive. Its ability to absorb and dissipate UV radiation, along with its thermal stability, makes it an essential component in the production of polymers and plastics.
Check Digit Verification of cas no
The CAS Registry Mumber 53566-09-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,5,6 and 6 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 53566-09:
(7*5)+(6*3)+(5*5)+(4*6)+(3*6)+(2*0)+(1*9)=129
129 % 10 = 9
So 53566-09-9 is a valid CAS Registry Number.

A series of 2-hydroxyarylidene-4-cyclopentene-1,3-diones were designed, synthesized, and evaluated with respect to protein tyrosine kinase (PTK) inhibition, mitochondrial toxicity, and antitumor activity. Our results show that the cyclopentenedione-derived TX-1123 is a more potent antitumor tyrphostin and also shows lower mitochondrial toxicity than the malononitrile-derived AG17, a potent antitumor tyrphostin. The O-methylation product of TX-1123 (TX-1925) retained its tyrphostin-like properties, including mitochondrial toxicity and antitumor activities. However, the methylation product of AG17 (TX-1927) retained its tyrphostin-like antitumor activities, but lost its mitochondrial toxicity. Our comprehensive evaluation of these agents with respect to protein tyrosine inase inhibition, mitochondrial inhibition, antitumor activity, and hepatotoxicity demonstrates that PTK inhibitors TX-1123 and TX-1925 are more promising candidates for antitumor agents than tyrphostin AG17.
