Chemical Properties

yellow to gold crystalline powder or needles


2-Nitrobenzenesulfenyl Chloride is used in the synthesis of α-amino phosphonic acids


CAUTION: This chloride is explosive, and the solvent has to be removed under reduced pressure. To a 500-ml, three-necked flask equipped with a mechanical stirrer, thermometer, gas addition tube, and condenser is added 200 ml of dry carbon tetrachloride, 30 gm (0.1 mole) of 2,2'-dinitrophenyl disulfide, and 0.05 gm of iodine as a catalyst. The suspension is heated to 50-60°C, and chlorine gas is added at such a flow rate that 10 gm (0.14 mole) is added over a 2-2^-hr period at this temperature. After this time, the solid starting disulfide finally goes into solution, and the warm dark yellow solution is filtered. The solution is cooled to 5°C, and the product that crystallizes out is filtered and dried to afford 25.2-27.0 gm (66-71%), m.p. 73-74.5°C.

Purification Methods

Recrystallise it from CCl4 (2mL/g), filter off the solution at 5o (recovery 75%). It has also been recrystallised from pet ether (b 40-60o), dried rapidly at 50o and stored in a brown glass bottle, sealed well and stored away from moisture.

Check Digit Verification of cas no

The CAS Registry Mumber 7669-54-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,6 and 9 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 7669-54:
137 % 10 = 7
So 7669-54-7 is a valid CAS Registry Number.

Synthesis and biological evaluation of nonsymmetrical aromatic disulfides as novel inhibitors of acetohydroxyacid synthase

46 Novel nonsymmetrical aromatic disulfides containing [1,3,4]thiadiazole or [1,3,4]oxadiazole groups were synthesized and their biological activities were evaluated as inhibitors of acetohydroxyacid synthase (AHAS, EC Besides their strong in vitro inhibition against plant AHAS, compounds 3e and 3f also display 80-100% post-emergence herbicidal activities in greenhouse bioassay at 1500 g/ha dosage. The assay of exogenous branched-chain amino acids supplementation on rape root growth of 3e suggests that the herbicidal activity has relationship with AHAS inhibition.
