2-Oxobutyric acid Usage And Synthesis

Chemical Properties

COLOURLESS TO ALMOST COLOURLESS CRYSTALS

Chemical Properties

2-Oxobutyric acid has a sweet, brown, caramel, creamy odor.

Occurrence

Reported found in beer and black tea.

Uses

A substrate for the determination of lactate dehydrogenase isoenzymes.This compound is suitable for lactate dehydrogenase (LDH) related research.

Uses

2-Oxobutyric acid (α-ketobutyric acid) may be used as an analytical reference standard for the determination of the analyte in K562 cells by high-performance liquid chromatography with fluorescence detection and in drinking water at low microgram per liter concentrations by ion chromatography technique.

Definition

ChEBI: A 2-oxo monocarboxylic acid that is the 2-oxo derivative of butanoic acid.

Taste threshold values

Taste characteristics at 25 ppm: sweet, brown, creamy, caramellic with a fatty nuance.

General Description

2-Oxobutyric acid is mainly found in the hydrolysates of proteins, reportedly being formed by the degradation of threonine.
