General Description
2,4-Pyridinedimethanol, also known as 2,4-Pyridinedimethanol and 4-hydroxymethylpyridine, is a chemical compound with the molecular formula C7H9NO2. It is a white to light yellow crystalline solid that is soluble in water and is commonly used as a pharmaceutical intermediate and a chelating agent. 2,4-Pyridinedimethanol is utilized in the production of a variety of drugs, including antihistamines, antimuscarinics, and anticholinergics. It is also employed in the synthesis of pesticides, dyes, and rubber chemicals. Additionally, this compound has been investigated for its potential antioxidant and anti-cancer properties. However, it is important to handle 2,4-Pyridinedimethanol with care, as it may cause irritation to the skin, eyes, and respiratory system upon exposure.
Check Digit Verification of cas no
The CAS Registry Mumber 21071-04-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,0,7 and 1 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 21071-04:
(7*2)+(6*1)+(5*0)+(4*7)+(3*1)+(2*0)+(1*4)=55
55 % 10 = 5
So 21071-04-5 is a valid CAS Registry Number.

Electron and Hydrogen Transfer Reductions of Some 2,4-Disubstituted Pyridines
Attia, A.,El-Salam, O. I. Abd,Youssef, T. E.
, p. 351 - 362 (2007/10/03)
New synthesis of 2,4-diacetylpyridine 1 was undertaken by Claisen condensation of 2,4-diethoxycarbonylpyridine 2a with ethyl acetate, followed by hydrolysis of the intermediate 3. Reduction of 1 with zinc or its salt in hydrochloric, formic or acetic acids afforded mixtures of the ketocarbinol 4 dicarbinol 5 or diethyl 6 pyridine derivatives. Formation of 6 as the complete reduction product was chemically proved to proceed via 4 and 5. Electrochemical reduction of 2a leads to 2,4-dimethylpyridine 7, and that of 1 gave rise to a mixture of 5 and 6 along with 2,4-diethyl-1,2,5,6-tetrahydropyridine 8 and 2,4-diethylpiperidine 9. Finally, metal hydride reduction of 1 gave 5, and that of diesters 2 or diacid chloride 10 derivatives afforded 2,4-dihydroxymethylpyridine 11.
