一般描述
Acylation, an alternative to silylation, is the conversion of compounds that contain active hydrogens (-OH, -SH and -NH) into esters, thioesters, and amides through the action of a carboxylic acid or derivative. The presence of a carbonyl group adjacent to the halogenated carbons enhances electron capture detector (ECD) response. Acylation has many benefits:
Hydrogen chloride-1-butanol is a reagent utilized to form fragmentation-directing derivatives for GC/MS analysis.
- It improves the stability of compounds by protecting unstable groups.
- It may confer volatility on substances such as carbohydrates or amino acids, which have so many polar groups that they are non-volatile and normally decompose on heating.
- It assists in separations not possible with underivatized compounds.
- Compounds are detectable at very low levels with an ECD.
Hydrogen chloride-1-butanol is a reagent utilized to form fragmentation-directing derivatives for GC/MS analysis.
应用
Hydrogen chloride - 1-butanol solution has been used for butylation of amino acids during blood sample analysis for determination of ethylenediaminetetraacetic acid using mass spectrometry.
