In 2022,Sheikh, Hamdullah Khadim; Arshad, Tanzila; Habib, Uzma; Mohammad, Zainab Sher; Siddiqui, Maaz Uddin Ahmed; Hassan, Mohtasheemul published an article in Pakistan Journal of Pharmaceutical Sciences. The title of the article was 《Colorimetric chromophoric rapid detection of SARS-CoV-2 through breath analysis》.Recommanded Product: 7720-39-0 The author mentioned the following in the article:
Early and rapid detection of SARS-CoV-2 in an infected person is one fundamental part of the strategy against the spread of this virus. As of now, the usual practice is to carry out polymerase chain reaction (PCR) test which provides results in 24-48 h. Hence, there exists a crucial need for rapid and immediate screening of people suspected to be infected. Presence of volatile organic compounds (VOCs) in the exhaled breath can be one such prospect for detection of virus. In this paper, we have designed chromophoric adducts of VOC′s in the exhaled breath that can be formed for colorimetric detection of SARS-CoV-2. We noted the bathochromic shift in λ (nm) of VOC mols. upon chromophore formation for colorimetric detection. If adapted, this research work will result in low cost solution to the requirement of immediate detection of SARS-CoV-2, hence cost and time of testing will be reduced, compared to PCR and antibodies tests. Also VOC′s detection in early stage of infection where symptoms are not visible can be advantageous. The experimental part of the paper was very detailed, including the reaction process of 1H-Imidazol-2-amine(cas: 7720-39-0Recommanded Product: 7720-39-0)
1H-Imidazol-2-amine(cas: 7720-39-0) belongs to anime. Large quantities of aliphatic amines are made synthetically. The most widely used industrial method is the reaction of alcohols with ammonia at a high temperature, catalyzed by metals or metal oxide catalysts (e.g., nickel or copper). Mixtures of primary, secondary, and tertiary amines are thereby produced.Recommanded Product: 7720-39-0
