The invention is used in particular in biology, pharmacology and chemistry to determine the structure and/or substance class and/or the chemical properties of unknown substances found.doi:WO2012126451 A2BÖCKER, SebastianSCHEUBERT, KerstinRASCHE, Florian...
To address this limitation, in silico spectra (i.e., MS/MS or MS2 spectra), predicted via Competitive Fragmentation Modeling-ID (CFM-ID) algorithms, were generated for compounds within the U.S. Environmental Protection Agency's (EPA) Distributed Structure-Searchable Toxicity (DSSTox) database (...
MA Hamdalla,II Mandoiu,DW Hill,S Rajasekaran,DF Grant 摘要: The structural identification of unknown biochemical compounds in complex biofluids continues to be a major challenge in metabolomics research. Using LC/MS, there are currently two major options for solving this problem: searching small ...
so we have C
Is there a SIMPLE chemical test that can be done to identify if an unknown chemical is an ester? I've heard of this but cant confirm if it is true: Add NaOH and reflux. Then add some 1M sulphuric acid, and if there's a precipitate, that identifies the presence of an ester. ...

The higher Fmax values of C2 and C3 in the orchards can be attributed to the accumulation of plant materials, which is associated with high hydrophobicity in the upper soil layer. The non-cultivated plots in this region were characterized by very low amounts of vegetation and this may explain...
While in many cases the use of pre- servatives has been shown to not impact DNA quality or yield [33], they often introduce biases toward the detec- tion of specific microorganisms. In 2015, Choo et al. [40] compared commonly used microbiome preserva- tives for stool and found that ...
I found this place after spending hours tearing my hair out, and then realized there surely must be people like me out there who despise unknowns as I do. So I come to you for help. I don't have a scanner, but I can describe for you the absorbancies of the IR, HNMR and CNMR....
