pentanoic acid, 2-hydroxy-, methyl ester

2-Hydroxyvalerate Methyl Ester (Pentanoic acid, 2-hydroxy-, methyl ester) Product Description

1. Basic Information

Chinese Name: 2-Hydroxyvalerate Methyl Ester

English Name: Methyl 2-hydroxyvalerate (or Methyl 2-hydroxy pentanoate)

CAS No.: 13811-71-7

Molecular Formula: C₆H₁₂O₃

Molecular Weight: 132.16 g/mol

2. Physical and Chemical Properties

Appearance and Properties: Colorless to light yellow transparent liquid at room temperature, with a slight fruity aroma or special smell typical of ester compounds.

Melting Point: No clear public data (presumably a low melting point liquid).

Boiling Point: About 195-200℃ (normal pressure), the specific value may vary slightly due to different purity.

Density: 1.03-1.05 g/cm³ (25℃).

Solubility: Soluble in organic solvents such as ethanol, ether, and acetone, slightly soluble in water (because the hydroxyl groups in the molecule can form hydrogen bonds, but the ester group is more hydrophobic).

Stability: Stable at room temperature and pressure, but avoid contact with strong oxidants, strong acids or strong bases to prevent hydrolysis or oxidation reactions.

3. Synthesis method

Typical route: Prepared by esterification reaction of 2-hydroxyvaleric acid and methanol under the action of an acidic catalyst (such as sulfuric acid, p-toluenesulfonic acid), and then neutralized and distilled for purification.

Other methods: It can also be prepared by esterification reaction of Grignard reagent or other hydroxycarboxylic acid derivatives with methanol.

4. Uses

Organic synthesis intermediate: used to prepare drugs, spices, pesticides and functional materials. For example, the hydroxyl and ester groups in its molecules can participate in acylation, alkylation, condensation and other reactions to derive complex structure compounds.

Spice industry: It may be used as a component of edible or daily spices, and its ester aroma can be used to prepare fruity or floral flavors (must meet relevant safety standards).

Solvent or reaction medium: Due to its good solubility, it can be used as a solvent for some organic reactions.
