Descrizione

Descrizione generale

2,3-Butanediol is a chiral compound which is extensively utilized in chemical feedstocks and liquid fuels.[1]

Applicazioni

2,3-Butanediol may be used as a reference standard for the determination of 2,3-butanediol in:

• ′Fino′ sherry wine by rotatory and continuous liquid−liquid extraction (LLE) and headspace solid-phase microextraction (HS-SPME) combined with gas chromatography-mass spectrometry (GC-MS).[2]
• Cell cultures as well as fermentation broths by high performance anion-exchange chromatography with pulsed amperometric detection (HPAE-PAD).[3]
• Cocoa (Theobroma cacao L.) by HS-SPME-GC-MS with principal component analysis (PCA).[4]
• Vinegar samples by HS-SPME combined with GC-MS in electron impact ionization (EI+) mode.[5]
