Volatile organic compounds (VOC) harm human health seriously in the air. Therefore, it is essential to recognize VOC gases qualitatively and quantitatively. The dynamic measurement method can improve selectivity of metal oxide semiconductor (MOS) gas sensors VOC, but there a problem insufficient number characteristic peaks. From experimental point view, primary judgment basis for correct qualit...

Simple synthesis and biological activities of modafinil derivatives are described. The key reactions include condensation of acid and propargyl alcohol, subsequent 1,3-dipolar cycloaddition reaction of alkynes and (3-azido-propyl)cyclohexane or (4-azido-butyl)benzene in the presence of sodium ascorbate and CuSO₄·5H₂O in excellent yield. They were then evaluated for the suppression of LPS-induce...

Hand eczema is a common occupational skin disease in healthcare workers. This is often the result of repeated contact with irritants, such as water; however, contact allergy can also be the underlying cause. In this report, we describe a patient with occupational hand eczema, caused by contact allergy to 1-propanol (CAS no. 71-23-8; synonyms n-propanol and n-propyl alcohol), which was present i...

Ethyl carbamate and a series of related compounds were given in single intraperitoneal doses to pregnant Syrian hamsters on Day 8 of gestation, and fetuses were examined for malformations on Day 13 of gestation. Urethan produced a variety of malforma tions and growth retardation. Of the compounds modified in the carboethoxy end, n-propyl carbamate was as teratogenic as the ethyl carbamate, and ...
