2,3-dimethyl-4-phenylazoisoxazol-5-one is a synthetic organic compound characterized by its unique chemical structure. It is a derivative of isoxazolone, a heterocyclic compound with a five-membered ring containing two oxygen atoms and one nitrogen atom. The molecule features two methyl groups (-CH3) at the 2nd and 3rd positions, and a phenylazo group (-N=N-C6H5) attached to the 4th position. 2,3-dimethyl-4-phenylazoisoxazol-5-one is often used as a chromophore in the synthesis of dyes and pigments due to its ability to absorb light in the visible spectrum, resulting in color. Its chemical properties and reactivity make it a valuable intermediate in the production of various colorants for industrial applications, such as textiles, plastics, and inks.
The CAS Registry Mumber 1747-61-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,4 and 7 respectively; the second part has 2 digits, 6 and 1 respectively. Calculate Digit Verification of CAS Registry Number 1747-61: (6*1)+(5*7)+(4*4)+(3*7)+(2*6)+(1*1)=91 91 % 10 = 1 So 1747-61-1 is a valid CAS Registry Number.
