19829-74-4 Usage

General Description

4,6-Dihydroxyisophthalic acid is a chemical substance also known as 4,6-Dihydroxybenzene-1,3-dicarboxylic acid. This organic compound is often used in scientific and industrial settings, such as in the production of certain types of polymers or resins. The compound features a benzene ring with two hydroxyl groups and two carboxylic acid groups attached, which contributes to its diverse reactivity and potential uses. Notably, 4,6-Dihydroxyisophthalic acid may pose certain health risks if improperly handled, and thus its use is generally restricted to experienced professionals.

Check Digit Verification of cas no

The CAS Registry Mumber 19829-74-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,8,2 and 9 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 19829-74:
(7*1)+(6*9)+(5*8)+(4*2)+(3*9)+(2*7)+(1*4)=154
154 % 10 = 4
So 19829-74-4 is a valid CAS Registry Number.

Benzoxazinones as potent positive allosteric AMPA receptor modulators: Part I

Mueller, Rudolf,Li, Yong-Xin,Hampson, Aidan,Zhong, Sheng,Harris, Clayton,Marrs, Christopher,Rachwal, Stanislaw,Ulas, Jolanta,Nielsson, Lena,Rogers, Gary

AMPA receptors (AMPARs) are an increasingly important therapeutic target in the CNS. Aniracetam, the first identified potentiator of AMPARs, led to the rigid and more potent CX614. This lead molecule was optimized in order to increase affinity towards the

Synthesis of fused 2-(2′-hydroxyphenyl)benzoxazole derivatives: the impact of meta-/para-substitution on fluorescence and zinc binding

Abeywickrama, Chathura S.,Pang, Yi

, p. 3518 - 3522 (2016)

A fused bis[2-(2′-hydroxyphenyl)benzoxazole] bis(HBO) 3 was synthesized via reaction of 4,6-dihydroxyisopthalic acid with 2-amnophenol in the presence polyphosphoric acid (PPA). In bis(HBO) 3, two benzoxazol-2-yl groups are connected via meta-phenylene, i

Record High Hydrogen Storage Capacity in the Metal-Organic Framework Ni2(m-dobdc) at Near-Ambient Temperatures

Kapelewski, Matthew T.,Run?evski, Tom?e,Tarver, Jacob D.,Jiang, Henry Z. H.,Hurst, Katherine E.,Parilla, Philip A.,Ayala, Anthony,Gennett, Thomas,Fitzgerald, Stephen A.,Brown, Craig M.,Long, Jeffrey R.

Hydrogen holds promise as a clean alternative automobile fuel, but its on-board storage presents significant challenges due to the low temperatures and/or high pressures required to achieve a sufficient energy density. The opportunity to significantly reduce the required pressure for high density H2 storage persists for metal-organic frameworks due to their modular structures and large internal surface areas. The measurement of H2 adsorption in such materials under conditions most relevant to on-board storage is crucial to understanding how these materials would perform in actual applications, although such data have to date been lacking. In the present work, the metal-organic frameworks M2(m-dobdc) (M = Co, Ni; m-dobdc4- = 4,6-dioxido-1,3-benzenedicarboxylate) and the isomeric frameworks M2(dobdc) (M = Co, Ni; dobdc4- = 1,4-dioxido-1,3-benzenedicarboxylate), which are known to have open metal cation sites that strongly interact with H2, were evaluated for their usable volumetric H2 storage capacities over a range of near-ambient temperatures relevant to on-board storage. Based upon adsorption isotherm data, Ni2(m-dobdc) was found to be the top-performing physisorptive storage material with a usable volumetric capacity between 100 and 5 bar of 11.0 g/L at 25 °C and 23.0 g/L with a temperature swing between -75 and 25 °C. Additional neutron diffraction and infrared spectroscopy experiments performed with in situ dosing of D2 or H2 were used to probe the hydrogen storage properties of these materials under the relevant conditions. The results provide benchmark characteristics for comparison with future attempts to achieve improved adsorbents for mobile hydrogen storage applications.

Polyhydrazide-Based Organic Nanotubes as Efficient and Selective Artificial Iodide Channels

Aksimentiev, Aleksei,Chen, Feng,Joshi, Himanshu,Roy, Arundhati,Shen, Jie,Ye, Ruijuan,Zeng, Huaqiang

supporting information, p. 4806 - 4813 (2020/02/11)

Reported herein is a series of pore-containing polymeric nanotubes based on a hydrogen-bonded hydrazide backbone. Nanotubes of suitable lengths, possessing a hollow cavity of about a 6.5 ? diameter, mediate highly efficient transport of diverse types of anions, rather than cations, across lipid membranes. The reported polymer channel, having an average molecular weight of 18.2 kDa and 3.6 nm in helical height, exhibits the highest anion-transport activities for iodide (EC50=0.042 μm or 0.028 mol % relative to lipid), whcih is transported 10 times more efficiently than chlorides (EC50=0.47 μm). Notably, even in cholesterol-rich environment, iodide transport activity remains high with an EC50 of 0.37 μm. Molecular dynamics simulation studies confirm that the channel is highly selective for anions and that such anion selectivity arises from a positive electrostatic potential of the central lumen rendered by the interior-pointing methyl groups.
