Analytical Techniques for Combinatorial Chemistry:  Quantitative Infrared Spectroscopic Measurements of Deuterium-Labeled Protecting Groups

open access: closedJournal of the American Chemical Society, 1996
Infrared microspectroscopy has been developed as a powerful, nondestructive technique for the quantitative analysis of solid-phase, resin-bound chemical reactions. The synthesis and/or application of deuterium isotope containing protecting groups, including acetyl-d3 chloride, benzoyl-d5 chloride, and 2-[[[(tert-butyl-d9)oxy]carbonyl]oximino]-2 ...

UZM-13, UZM-17, UZM-19 and UZM-25: synthesis and structure of new layered precursors and a zeolite discovered via combinatorial chemistry techniques

open access: closed, 2007
Abstract A combinatorial chemistry investigation screening the abilities of the diethyldimethylammonium (DEDMA), ethyltrimethylammonium (ETMA), and [Me 3 N(CH 2 ) 4 NMe 3 ] 2+ (diquat-4, DQ-4) cations to form zeolites over a range of conditions was carried out.

Combinatorial chemistry methods for coating development VI. Correlation of high throughput screening methods with conventional measurement techniques

open access: closedProgress in Organic Coatings, 2003
Abstract Combinatorial chemistry has proven to be a valuable tool for the development of new compounds. In the pharmaceutical industry, where combinatorial chemistry began, the approach has been instrumental in the high-speed development of new drugs.

Direct-Injection NMR (DI-NMR):  A Flow NMR Technique for the Analysis of Combinatorial Chemistry Libraries

open access: closedJournal of Combinatorial Chemistry, 2000
A new tool for analyzing compound libraries by NMR has been developed. Aliquots of solution-state samples (between 120 and 350 microL) are directly injected, using a standard liquids handler, into an NMR (LC-NMR) flow probe. Automated NMR software tracks--and suppresses--intense signals arising from the nondeuterated solvents used (if any) and acquires
