4-Nitrophenylsulphur trifluoride (4-NPTSF) is a chemical compound with the molecular formula C6H4F3NO3S. It is a derivative of phenylsulphur trifluoride, where a nitro group is attached to the para position of the benzene ring. 4-nitrophenylsulphur trifluoride is known for its reactivity and is often used as a reagent in organic synthesis, particularly in the preparation of various sulfur-containing compounds. 4-NPTSF is a colorless to pale yellow solid that is sensitive to moisture and light, and it is typically handled under anhydrous conditions. Due to its reactivity, it is important to use appropriate safety measures when working with 4-NPTSF, including the use of gloves, eye protection, and a well-ventilated workspace.

Check Digit Verification of cas no

The CAS Registry Mumber 1526-28-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,2 and 6 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1526-28:
(6*1)+(5*5)+(4*2)+(3*6)+(2*2)+(1*8)=69
69 % 10 = 9
So 1526-28-9 is a valid CAS Registry Number.

A new method for the synthesis of organosulfur trifluorides

Pashinnik,Martyniuk,Tabachuk,Shermolovich,Yagupolskii

, p. 2505 - 2509 (2003)

Simple, convenient and universal method of the different types of organosulfur trifluorides synthesis, with common formula RSF3 where R = dialkylamino group, aromatic or heterocyclic radical, was elaborated. The method consists in the reaction of thiosulf

Process for the synthesis of aryl sulfurpentafluorides

-

Page 12, (2008/06/13)

A process is described for the synthesis of an aryl sulfur pentafluoride compound. In one embodiment of the present invention, there is provided a process for preparing an aryl sulfurpentafluoride compound comprising: combining an at least one aryl sulfur compound with a fluorinating agent to at least partially react and form an intermediate aryl sulfurtrifluoride product; and exposing the intermediate aryl sulfurtrifluoride product to the fluorinating agent and optionally a fluoride source to at least partially react and form the aryl sulfurpentafluoride compound.
