14049-39-9 Usage
Uses
Used in Semiconductor Industry:
Trifluorobromosilane is used as a vapor deposition agent for the production of silicon films in electronic devices. Its high reactivity allows for the creation of thin, uniform, and pure silicon layers, which are essential for the performance of semiconductor devices.
Used as a Precursor in Material Production:
In addition to its role in semiconductor manufacturing, trifluorobromosilane serves as a precursor in the synthesis of various silicon-containing materials. It is utilized in the production of coatings, polymers, and ceramics, where its reactivity and ability to form stable silicon compounds contribute to the development of advanced materials with specific properties.
Safety Precautions:
Due to its toxic and corrosive nature, trifluorobromosilane requires careful handling to prevent irritation to the skin, eyes, and respiratory system. Proper safety measures, including the use of personal protective equipment and controlled environments, should be implemented when working with this chemical compound.
Check Digit Verification of cas no
The CAS Registry Mumber 14049-39-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,0,4 and 9 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 14049-39:
(7*1)+(6*4)+(5*0)+(4*4)+(3*9)+(2*3)+(1*9)=89
89 % 10 = 9
So 14049-39-9 is a valid CAS Registry Number.

Reaction of Silicon Difluoride with Halogens: a Reinvestigation
Suresh, Bettadapura S.,Thompson, James Charlton
, p. 1123 - 1126 (2007/10/02)
Reactions of SiF2 with halogens have been reinvestigated by both co-condensation and gas-phase methods.The co-condensation method yields a number of fluorohalogenosilanes including mono-, di-, and higher silane derivatives.These compounds contain SiF, SiF2, and SiF3 units.The reactivity towards SiF2 decreases from chlorine through bromine to iodine.While chlorine and bromine give rise to a number of fluorohalogenosilanes, iodine yields only the monosilane derivatives.In contrast, the gas-phase reaction do not progress to any appreciable extent.The products have been characterized by mass spectrometry and 19F and 29Si n.m.r. spectroscopy.Many have been identified for the first time.
