Physical and Chemical Properties
|
Appearance |
Colorless to pale yellow liquid at room temperature. |
|
Melting Point |
Approximately –40°C to –41°C. |
|
Boiling Point |
Typically ranges from 244°C to 254°C (slight variation across sources). |
|
Density |
About 0.928 g/mL (at 20°C). |
|
Solubility |
Soluble in organic solvents such as ethanol and diethyl ether. It is moisture-sensitive and hydrolyzes slowly in water to form hexanoic acid. |
Main Applications
Organic Synthesis Reagent
Primarily used to introduce the hexanoyl group into other molecules for chemical modification.
Polymer Modification
Reacts with hydroxyl or amino groups in polymers (e.g., chitosan) to alter hydrophobicity or mechanical properties.
Chromatographic Analysis
Used as a derivatization reagent for alcohols and amines to form esters and amides, improving detection and separation.
Safety and Storage
Hazards
Corrosive; may cause severe skin burns and eye damage (GHS05). Also may cause skin sensitization (H317).
Storage
Due to its moisture sensitivity, it should be stored sealed in a cool, dry place under inert gas protection. Typical shelf life is 2–3 years.
