Ethers lack the hydroxyl groups of alcohols. Without the strongly polarized O―H bond, ether molecules cannot engage in hydrogen bonding with each other. 111-90-0, formula is C6H14O3, Name is Diethylene Glycol Monoethyl Ether. Ethers do have nonbonding electron pairs on their oxygen atoms, however, and they can form hydrogen bonds with other molecules (alcohols, amines, etc.) that have O―H or N―H bonds. Name: Diethylene Glycol Monoethyl Ether.

ObjectiveUnderstanding the potential inhalation toxicity of poorly characterized aerosols is challenging both because aerosols may contain numerous chems. and because it is difficult to predict which chems. may present significant inhalation toxicity concerns at the observed levels. We have developed a novel systematic procedure to address these challenges through non-targeted chem. anal. by two-dimensional gas chromatog.-time-of-flight mass spectrometry (GC x GC-TOFMS) and assessment of the results using publicly available toxicity data to prioritize the tentatively identified detected chems. according to potential inhalation toxicity. Materials and MethodsThe procedure involves non-targeted chem. anal. of aerosol samples utilizing GC x GC-TOFMS, which is selected because it is an effective technique for detecting chems. in complex samples and assigning tentative identities according to the mass spectra. For data evaluation, existing toxicity data (e.g. from the U.S. Environmental Protection Agency CompTox Chems. Dashboard) are used to calculate multiple toxicity metrics that can be compared among the tentatively identified chems. These metrics include hazard quotient, incremental lifetime cancer risk, and metrics analogous to hazard quotient that we designated as exposure-(toxicol. endpoint) ratios. Results and DiscussionWe demonstrated the utility of our procedure by detecting, identifying, and prioritizing specific chems. of potential inhalation toxicity concern in the mainstream smoke generated from the machine-smoking of marijuana blunts. ConclusionBy designing a systematic approach for detecting and identifying numerous chems. in complex aerosol samples and prioritizing the chems. in relation to different inhalation toxicol. endpoints, we have developed an effective approach to elucidate the potential inhalation toxicity of aerosols.
Name: 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.
