1-Butylboronic acid is used as a reagent for preparation of volatile derivatives of diols, e.g. carbohydrates, for GC and mass spectrometry and to prepare chiral oxazaborolidines. It is a precursor to unsymmetric borinic acids, which are inhibitors of serine proteases. Can be used as a transport carrier in membrane-based sugar separations and as an analytical reagent in the determination of serum glucose.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
Applications
1-Butylboronic acid is used as a reagent for preparation of volatile derivatives of diols, e.g. carbohydrates, for GC and mass spectrometry and to prepare chiral oxazaborolidines. It is a precursor to unsymmetric borinic acids, which are inhibitors of serine proteases. Can be used as a transport carrier in membrane-based sugar separations and as an analytical reagent in the determination of serum glucose.
Solubility
Soluble in water.
Notes
Keep container tightly sealed. Store in cool, dry conditions in well sealed containers. It is hygroscopic in nature. Incompatible with oxidizing agents. Store under dry inert gas.
