How to Constrain the Molecular Structure Search Space with Chemical Labeling

Unlocking the chemical ‘dark matter’ in metabolomics is a persistent challenge. A new approach addresses this by integrating derivatisation reactions for chemical labeling directly into the mass spectrometry workflow. It provides crucial structural information which is fed into small molecule annotation tools like SIRIUS to significantly constrain the molecular structure search space and boost annotation accuracy, even for previously undiscovered compounds. This powerful approach offers a scalable solution to unlock the vast, uncharted chemical space of the metabolome.

How to Manually Refine Structures for Better Annotation

Do you ever look at the best hit from a structure database search and instantly know how to improve it? In SIRIUS, your chemical intuition just got a powerful new tool: the Structure Sketcher. This tutorial will demonstrate how you can leverage your own chemical knowledge to manually modify a candidate structure to achieve even better annotation results.

How to Screen for Transformation Products with SIRIUS

Detecting transformation products is crucial for environmental monitoring, as these byproducts can be more toxic and persistent than their precursor compounds. This tutorial walks you through using SIRIUS for a non-targeted combined precursor and transformation product screening, from generating a transformation product database to analysing LC-HRMS data in SIRIUS and validating results.
