2(1H)-Pyridineselone, also known as 2-pyridoneselone or 2-pyridone-5-sulfonic acid, is a chemical compound with the molecular formula C5H5NO3S. It is a derivative of pyridine, a heterocyclic aromatic compound containing a nitrogen atom in a six-membered ring. 2(1H)-Pyridineselone is characterized by the presence of a sulfonic acid group (-SO3H) at the 5-position of the pyridine ring, which imparts acidic properties to the molecule. 2(1H)-Pyridineselone has potential applications in various fields, including pharmaceuticals, agrochemicals, and as intermediates in the synthesis of other organic compounds. Due to its unique structure and reactivity, 2(1H)-Pyridineselone can be used in the development of new drugs, dyes, and other specialty chemicals.

Check Digit Verification of cas no

The CAS Registry Mumber 2044-26-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,4 and 4 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 2044-26:
(6*2)+(5*0)+(4*4)+(3*4)+(2*2)+(1*6)=50
50 % 10 = 0
So 2044-26-0 is a valid CAS Registry Number.

, (2008/06/13)

The present invention relates to a single source metalloorganic precursor compound of the formula: wherein M is selected form the Group 14 elements of Germanium, Tin or Lead; A and R are independently selected from: amide, alkyl having from 1 to 20 carbon atoms, aryl, substituted aryl, or -Q'-2-NR'Ln (n=1-4) wherein L is selected from nothing or a Lewis base ligand; Q and Q' are each independently selected from Group VIa elements of sulfur, selenium, or tellurium; and 2-NR and 2-NR' are each independently selected from N-heterocyclic aryl or its derivatives. Methods of producing these compounds are also disclosed. These precursor materials provide in a single compound the binary, tertiary, or quaternary metals in a ratio to each other that is controllable by a judicious choice of metal atoms and organic substituents. The metal alloys are useful in a variety for electronic applications, particularly in semiconductors and solar energy.
