3-Hydroxy-N-methylpyridinium chloride, also known as 3-HMPCl, is a chemical compound with the molecular formula C6H7ClNO. It is a derivative of pyridinium, a heterocyclic compound consisting of a six-membered aromatic ring with one nitrogen atom. In this specific compound, a hydroxyl group (-OH) is attached to the third carbon atom, and a methyl group (-CH3) is connected to the nitrogen atom through an N-methyl bond. The chloride ion (Cl-) is present as a counterion, forming an ionic bond with the positively charged pyridinium ring. 3-HMPCl is a white crystalline solid that is soluble in water and polar organic solvents. It has potential applications in various fields, including pharmaceuticals, agrochemicals, and materials science, due to its unique chemical properties and reactivity.
The CAS Registry Mumber 7295-78-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,9 and 5 respectively; the second part has 2 digits, 7 and 8 respectively. Calculate Digit Verification of CAS Registry Number 7295-78: (6*7)+(5*2)+(4*9)+(3*5)+(2*7)+(1*8)=125 125 % 10 = 5 So 7295-78-5 is a valid CAS Registry Number.
