HBTU activates carboxylic acids by forming a stabilized HOBt (Hydroxybenzotriazole) leaving group. The activated intermediate species attacked by the amine during aminolysis is the HOBt ester. To create the HOBt ester, the carboxyl group of the acid attacks the imide carbonyl carbon of HBTU.
Spectrochemistry is the application of spectroscopy in several fields of chemistry. It includes analysis of spectra in chemical terms, and use of spectra to derive the structure of chemical compounds, and also to qualitatively and quantitively analyze their presence in the sample.
Propylene glycol methyl ether acetate (PGMEA, 1-methoxy-2-propanol acetate) is a P-type glycol ether used in inks, coatings, and cleaners. It is sold by Dow Chemical under the name Dowanol PMA, [3] by Shell Chemical under the name methyl proxitol acetate, [4] [5] and by Eastman under the name PM Acetate.
Benzenesulfonic acid (conjugate base benzenesulfonate) is an organosulfur compound with the formula C 6 H 6 O 3 S.It is the simplest aromatic sulfonic acid.It forms white deliquescent sheet crystals or a white waxy solid that is soluble in water and ethanol, slightly soluble in benzene and insoluble in nonpolar solvents like diethyl ether.
Ultraviolet-visible() absorption spectroelectrochemistry is a technique that studies the absorption of electromagnetic radiation in the UV-Vis regions of the spectrum, providing molecular information related to the electronic levels of molecules. [10]
Imidazolidine is a heterocyclic compound (CH 2) 2 (NH) 2 CH 2.The parent imidazolidine is lightly studied, but related compounds substituted on one or both nitrogen centers are more common.
APTES is a toxic compound with an MSDS health hazard score of 3. APTES fumes are destructive to the mucous membranes and the upper respiratory tract, and should be used in a fume hood with gloves.
The Review of Particle Physics [2] (formerly Review of Particle Properties, Data on Particles and Resonant States, and Data on Elementary Particles and Resonant States) is a voluminous, 1,200+ page reference work which summarizes particle properties and reviews the current status of elementary particle physics, general relativity and big-bang cosmology.
