Safety of 3,3-Bis(3,5-dibromo-4-hydroxy-2-methylphenyl)-3H-benzo[c][1,2]oxathiole 1,1-dioxide. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: 3,3-Bis(3,5-dibromo-4-hydroxy-2-methylphenyl)-3H-benzo[c][1,2]oxathiole 1,1-dioxide, is researched, Molecular C21H14Br4O5S, CAS is 76-60-8, about Printed sensor labels for colorimetric detection of ammonia, formaldehyde and hydrogen sulfide from the ambient air.
We present a novel method to monitor the exposure to toxic gases in ambient air based on a visible color change of a colorimetric gas sensor, which can be evaluated by the camera of a smartphone, stationary reader or even naked eye. This sensor consists of a disposable paper tag or plastic card and a gas sensitive material, which has been deposited by a screen-printing process. The integration of the gas sensitive layer into the machine-readable pattern of a QR-like code that incorporates color references for color calibration; makes it suitable for quant. as well as illumination and camera independent evaluation of the color change due to the reaction with the target gas. This work focusses on the development of printable pastes for the detection of ammonia , formaldehyde and hydrogen sulfide for the application in a colorimetric sensor label. NH3 and CH2O are detected with com. available pH sensitive color dyes. The alk. gas NH3 is tracked by the reaction with a pH indicator directly, while CH2O is detected by an intermediate reaction of CH2O with a primary amine through nucleophilic addition For the detection of H2S, an immobilized copper(II) complex of the azo dye 1-(2-pyridylazo)-2-naphtol (H-PAN) is synthesized. The color change of the printed sensors labels is characterized by the evaluation of RGB values taken with an in-situ readout station using a smartphone camera.
This literature about this compound(76-60-8)Safety of 3,3-Bis(3,5-dibromo-4-hydroxy-2-methylphenyl)-3H-benzo[c][1,2]oxathiole 1,1-dioxidehas given us a lot of inspiration, and I hope that the research on this compound(3,3-Bis(3,5-dibromo-4-hydroxy-2-methylphenyl)-3H-benzo[c][1,2]oxathiole 1,1-dioxide) can be further advanced. Maybe we can get more compounds in a similar way.
