Ethers can again be classified into two varieties: if the alkyl or aryl groups are the same on both sides of the oxygen atom, 111-90-0, formula is C6H14O3, Name is Diethylene Glycol Monoethyl Ether. Then it is a simple or symmetrical ether, whereas if they are different, the ethers are called mixed or unsymmetrical ethers. Recommanded Product: Diethylene Glycol Monoethyl Ether.
Doty, Anna C.;Wilson, A. Dan;Forse, Lisa B.;Risch, Thomas S. research published 《 Biomarker Metabolites Discriminate between Physiological States of Field, Cave and White-nose Syndrome Diseased Bats》, the research content is summarized as follows. Anal. of volatile organic compound (VOC) emissions using electronic-nose (e-nose) devices has shown promise for early detection of white-nose syndrome (WNS) in bats. Tricolored bats, Perimyotis subflavus, from three sep. sampling groups defined by environmental conditions, levels of phys. activity, and WNS-disease status were captured temporarily for collection of VOC emissions to determine relationships between these combinations of factors and physiol. states, Pseudogymnoascus destructans (Pd)-infection status, and metabolic conditions. Physiol. active (non-torpid) healthy individuals were captured outside of caves in Arkansas and Louisiana. In addition, healthy and WNS-diseased torpid bats were sampled within caves in Arkansas. Whole-body VOC emissions from bats were collected using portable air-collection and sampling-chamber devices in tandem. Electronic aroma-detection data using three-dimensional Principal Component Anal. provided strong evidence that the three groups of bats had significantly different e-nose aroma signatures, indicative of different VOC profiles. This was confirmed by differences in peak numbers, peak areas, and tentative chem. identities indicated by chromatograms from dual-column GC-analyses. The numbers and quantities of VOCs present in whole-body emissions from physiol. active healthy field bats were significantly greater than those of torpid healthy and diseased cave bats. Specific VOCs were identified as chem. biomarkers of healthy and diseased states, environmental conditions (outside and inside of caves), and levels of physiol. activity. These results suggest that GC/E-nose dual-technologies based on VOC-detection and analyses of physiol. states, provide noninvasive alternative means for early assessments of Pd-infection, WNS-disease status, and other physiol. states.
Recommanded Product: Diethylene Glycol Monoethyl Ether, Diethylene glycol monoethyl ether appears as a colorless, slightly viscous liquid with a mild pleasant odor. Flash point near 190°F. Used to make soaps, dyes, and other chemicals.
Diethylene glycol monoethyl ether is a primary alcohol that is ethanol substituted by a 2-ethoxyethoxy group at position 2. It has a role as a protic solvent. It is a diether, a primary alcohol and a hydroxypolyether. It derives from a diethylene glycol., 111-90-0.
