220473-94-9 Usage
Chemical structure
Contains a thiol (sulfhydryl) group and a phenylazo group.
Thiol group
A sulfur atom bonded to a carbon atom, responsible for the distinct odor.
Phenylazo group
A nitrogen molecule double-bonded to a carbon atom, bonded to a phenyl (aromatic) ring.
Applications
Used in the production of dyes and pigments, synthesis of pharmaceuticals and agricultural chemicals, and as a chemical intermediate in various industrial processes.
Reactivity
Can be highly reactive due to the presence of the thiol group.
Toxicity
Potentially toxic if not properly managed.
Handling
Requires careful handling to avoid adverse effects.
Hazardous properties
May pose risks to human health and the environment if not handled properly.
Safety measures
Appropriate safety precautions should be taken when working with 1-Butanethiol, 4-[4-[(1E)-phenylazo]phenoxy]- (9CI), including the use of personal protective equipment (PPE) and proper disposal methods.
Regulatory information
May be subject to specific regulations and guidelines depending on the country or region, due to its potential hazards and applications.
Check Digit Verification of cas no
The CAS Registry Mumber 220473-94-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,4,7 and 3 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 220473-94:
(8*2)+(7*2)+(6*0)+(5*4)+(4*7)+(3*3)+(2*9)+(1*4)=109
109 % 10 = 9
So 220473-94-9 is a valid CAS Registry Number.

Reversible phototuning of ferromagnetism at Au-S interfaces at room temperature
Suda, Masayuki,Kameyama, Naoto,Suzuki, Motohiro,Kawamura, Naomi,Einaga, Yasuaki
, p. 160 - 163 (2008/09/18)
Out of nowhere: Significant photoinduced changes in ferromagnetism have been observed at the interfaces between gold nanoparticles (Au NPs) and azobenzene-derivatized thiols. These photomagnetic effects could be attributed to photoinduced changes in d-cha
