Specific Rotation Many organic molecules exhibit isomerism, which is a property shown by molecules that have an identical molecular formulas but distinct structural formula. Stereoisomerism is a subtype of this and arises due to the 3D arrangement of molecules in space. However, this form of ...
Under the protective nitrogen, mass loss of organic residues did not reach the plateau up to 500°C. Chit/curd/nanoHA was less stable than the chit/aga/nanoHA, initializing pyrolysis at a lower temperature (214 compared to 233°C), with mass loss peaking at 2.4%/°C compared with 1.9%/...

Double-walled metal-organic frameworks (MOFs), such as BUT-53(Co) to BUT-57(Co)1and BUT-58(Zn)1, with highly customizable and tunable porous structure, exhibit excellent trace adsorption for volatile organic compounds (VOCs) such as benzene due to their unique double-walled structure. For e...
Organic Chemistry Stereochemistry Enantiomeric Excess (ee): Percentage of Enantiomers from Specific Rotation with Practice Problems In the previous post, we discussedracemic mixtureswhich consist of equal amounts of twoenantiomers. Racemic mixturesarenot chiralas they are notoptically active. For example,...

In addition, as other dye-providing compounds than the above-described couplers and the compounds of the general formula (LI), dye-silver compounds may be used wherein an organic silver salt is linked to a dye (Research Disclosure, May 1978, pp. 54-58, etc.), azo dyes may be used wit...
(B) Shows graphical rotation of back side view of the accessible surface. The difference in charges observed in the structure of DehI and DehD may be influenced by its substrate specificity. This also distinguishes DehD from the DehI enzymes, which have highly basic entrances and highly ...
Briefly, the run was 30 min, and the mobile phase composition was as follows: 0.1% aqueous formic acid and 2.5% isopropyl alcohol in water (Sigma-Aldrich, Munich, Germany) (solvent A), and 0.1% formic acid and 2.5% isopropyl alcohol in acetonitrile (Romil Pure Chemistry, Cambridge, UK) ...
Chemistry (5-Bromo-2-methoxyphenyl)methanol (7a). A solution of sodium borohydride (0.94 g, 24.8 mmol, 1.0 equiv.) in H2O (30 mL) was added to a solution of the benzaldehyde derivative 6a (5.33 g, 24.8 mmol) in methanol (200 mL). After stirring at room temperature for 24 h, ...
