This module has been designed to introduce second-year organic chemistry students to the concepts of stereochemistry through the lens of the World Health Organization’s Model List of Essential ...

Organic chemistry is the study of the structure, properties, composition, reactions, and preparation of carbon-containing compounds. Most organic compounds contain carbon and hydrogen, but they may ...

The National Institute of Standards and Technology (NIST) has updated its database of chemical fingerprints, called mass spectra, that are used to identify unknown chemical compounds. The NIST Mass ...

The NIST Mass Spectral Library has expanded to include new human and plant metabolites, variants of fentanyl and other synthetic drugs. The National Institute of Standards and Technology (NIST) has ...

Gas chromatography (GC) is used for the analytical separation of volatile substances in the gaseous phase. This chromatographic technique is widely used in various fields of research and industrial ...

TOF is often used as a surrogate measurement for the presence of PFAS, due to the fact that analytical methods do not exist for detecting most PFAS and because naturally occurring fluorinated ...

Fertilizers manufactured from the sludgy leftovers of wastewater treatment processes can contain traces of potentially hazardous organic chemicals, according to a new study. The research provides one ...
