1,2,3,4-Tetrachloro-5-fluorobenzene is an organochlorine compound with the chemical formula C6Cl4F. It is a derivative of benzene, where four chlorine atoms and one fluorine atom are substituted for hydrogen atoms at the 1, 2, 3, 4, and 5 positions, respectively. 1,2,3,4-tetrachloro-5-fluorobenzene is characterized by its high stability and low reactivity due to the presence of electronegative chlorine and fluorine atoms, which can form strong electron-withdrawing groups. It is a colorless, crystalline solid with a melting point of 87-89°C. 1,2,3,4-Tetrachloro-5-fluorobenzene has potential applications in the synthesis of various chemicals, pharmaceuticals, and agrochemicals, as well as in the production of dyes and pigments. However, due to its persistence in the environment and potential health risks, it is essential to handle and dispose of 1,2,3,4-tetrachloro-5-fluorobenzene with caution, following proper safety guidelines and regulations.

2691-93-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2691-93-2 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 1 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 2691-93:
(6*2)+(5*6)+(4*9)+(3*1)+(2*9)+(1*3)=102
102 % 10 = 2
So 2691-93-2 is a valid CAS Registry Number.

Methylhexamethylenetetramine fluoride dihydrate: A new fluorodenitration reagent

Clark, James H.,Nightingale, David J.

, p. 91 - 93 (2007/10/03)

Methylhexamethylenetetramine fluoride dihydrate has been prepared by conventional methods. It is moderately soluble in polar aprotic solvents, and shows good thermal stability, enabling it to be dried. The reagent is capable of converting activated nitroaromatics to the corresponding fluoroaromatics, with a high selectivity to monofluorodenitration being observed with some polysubstituted aromatics.
