General Description
3,5-DICHLORO-2,6-DIFLUORO-4-PYRIDINOL is a chemical compound with the molecular formula C5H2Cl2F2NO. It is a white crystalline solid that is used as a pesticide and insecticide. 3,5-DICHLORO-2,6-DIFLUORO-4-PYRIDINOL is known for its effectiveness in controlling a wide range of pests, including insects, mites, and nematodes. It works by disrupting the nervous system of the target pests, leading to paralysis and eventual death. 3,5-DICHLORO-2,6-DIFLUORO-4-PYRIDINOL is commonly used in agricultural settings to protect crops and in public health efforts to control disease-carrying pests. However, it is important to handle this compound with care, as it can be toxic to humans and other non-target organisms.
Check Digit Verification of cas no
The CAS Registry Mumber 2693-61-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,9 and 3 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2693-61:
(6*2)+(5*6)+(4*9)+(3*3)+(2*6)+(1*1)=100
100 % 10 = 0
So 2693-61-0 is a valid CAS Registry Number.

Polyhalogenoaromatic Compounds. Part 50. Reactions of 4-Benzyloxytetrahalogenopyridines with Nucleophiles

Reaction of 4-benzyloxy-3,5-dichloro-2,6-difluoro- (1; R = CH2Ph) and 4-benzyloxytetrachloropyridine (2; R = CH2Ph) with various nucleophiles (N,N-dimethylhydrazine, piperidine, N,N,N',N'-tetramethylethane-1,2-diamine, triphenylphosphine) occurs unexpectedly at the benzylic methylene group with alkyl-oxygen cleavage to give the corresponding benzylammonium (4) or triphenylphosphonium salt (9) respectively.The molecular structure of the salt derived from 4-benzyloxytetrachloropyridine and N,N-dimethylhydrazine was confirmed by an X-ray study.Preliminary experiments of ut ilising the benzyl cleavage for the preparation of various benzyl derivatives (PhCH2X; X = Cl,Br,I,CN,N3) are described.
