Increasing importation of food and the diversity of potential contaminants have necessitated more analytical testing of these foods. Historically, mass spectrometric methods for testing foods were confined to monitoring selected ions (SIM or MRM), achieving sensitivity by focusing on targeted ion signals. A limiting factor in this approach is that any contaminants not included on...

A 1H-1H COSY dataset of an unknown structure with protons offers many combinations of atom connectivity. The goal for the elucidator is to assess the correlations and narrow down a set of fragments that support the data. Below is a structural list for 1H to C to 1H connectivities. Absent from the list, heteroatoms such...

Like a COSY experiment, an HMBC dataset offers many combinations of atom connectivity. The goal for the elucidator is to assess each correlation and narrow down a set of fragments that support the data. For every correlation in a 1H-13C HMBC spectrum, an elucidator must decide whether a correlation corresponds to a 2J, 3J or...

When the spectral data is sparse, the list of potential candidate structures can seem endless. The task then becomes sifting through the spectral data as a means to filter the candidates. The purpose of this puzzle is to perform such a task. The following unknown compound with a mass of 380.1 +/- 0.5 Da comprises...

Deformulation, breaking down drug products into components is vital but traditionally slow and complex. Modern workflows integrate LC/MS, GC/MS, automation, and centralized databases to streamline analysis, boost reproducibility, and accelerate decisions. ACD/Labs software helps scientists cut effort, improve accuracy, and stay competitive.

Delicoferone A The fungi that colonize and reproduce in animal excrements are called Coprophilous fungi. They have specifically adapted to colonize in that environment, however, they can also be found on plants and soils when their spores are dispersed there. Jayanetti at co-workers [1] investigated cultures of such a fungus, the ex-type strain of Delitschia...
