3-Hydroxy-4H-1-benzopyran-4-one, also known as 3-hydroxyflavone, is a flavonoid derivative characterized by a benzopyranone core with a hydroxyl group at the 3-position. It serves as a key structural motif in many biologically active compounds, exhibiting properties such as antioxidant, anti-inflammatory, and fluorescent behavior. Its planar structure and ability to form hydrogen bonds make it a versatile scaffold in medicinal chemistry and materials science. 4H-1-Benzopyran-4-one, 3-hydroxy-'s reactivity and photophysical properties are often exploited in the design of sensors and probes.

13400-26-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 13400-26-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,4,0 and 0 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 13400-26:
(7*1)+(6*3)+(5*4)+(4*0)+(3*0)+(2*2)+(1*6)=55
55 % 10 = 5
So 13400-26-5 is a valid CAS Registry Number.
