1,4-Diethynyl-2,5-dimethoxybenzene(cas: 74029-40-6) belongs to ethers.Ethers do have nonbonding electron pairs on their oxygen atoms, and they can form hydrogen bonds with other molecules (alcohols, amines, etc.) that have O―H or N―H bonds. Recommanded Product: 1,4-Diethynyl-2,5-dimethoxybenzene The ability to form hydrogen bonds with other compounds makes ethers particularly good solvents for a wide variety of organic compounds and a surprisingly large number of inorganic compounds.

In 2012,Analytical Methods included an article by Chu, Chengchao; Wang, Xiu; Li, Shuai; Ge, Shenguang; Ge, Lei; Yu, Jinghua; Yan, Mei. Recommanded Product: 1,4-Diethynyl-2,5-dimethoxybenzene. The article was titled 《Synthesis, characterization of a novel phenyleneethynylene derivative and application in a fluorescence DNA sensor》. The information in the text is summarized as follows:

In this paper, a novel phenyleneethynylene derivative 4,4′-(2,5-dimethoxy-1,4-phenylene)bis(ethyne-2,1-diyl) dibenzoic acid (p-acid) was synthesized. IR spectroscopy (IR), NMR, photoluminescence (PL) spectroscopy and UV visible (UV-vis) spectroscopy were applied to characterize p-acid. The p-acid doped silica nanoparticle (p-acid@SiO2) was assembled in layer-by-layer (LBL) self-assembling processes using tetraethoxysilane (TEOS). Scanning electron microscope (SEM) and transmission electron microscope (TEM) were applied to characterize p-acid@SiO2. To research the practical applicability, a sample DNA sensor was constructed using p-acid@SiO2 label, in which the PL intensity response was proportion to the target-DNA (S2) concentration in the range of 0.05-1000 fM, with a detection limit of 20 pM. Furthermore, the DNA sensor showed high specificity, excellent stability, and good reproducibility. The p-acid@SiO2-based DNA sensor can also provide potential application for detection of other pathogen DNA. In the experimental materials used by the author, we found 1,4-Diethynyl-2,5-dimethoxybenzene(cas: 74029-40-6Recommanded Product: 1,4-Diethynyl-2,5-dimethoxybenzene)
