For professionals working with L-Proline Benzyl Ester Hydrochloride (CAS 16652-71-4), a thorough understanding of its technical specifications, physical and chemical properties, and safe handling procedures is essential for efficient and secure utilization. This compound, a key intermediate in various chemical syntheses, requires careful attention to detail from procurement to application.

Key Technical Specifications and Properties

When procuring L-Proline Benzyl Ester Hydrochloride, key specifications to confirm include:

• Chemical Name: L-Proline benzyl ester hydrochloride
• CAS Number: 16652-71-4
• Molecular Formula: C12H16ClNO2
• Molecular Weight: Approximately 241.71 g/mol
• Appearance: Typically a white to off-white powder. Variations might indicate differing purity levels or slight degradation, so consistency in appearance is a good initial quality indicator.
• Purity/Assay: Commonly specified as ≥98.0% or higher for pharmaceutical and high-grade research applications. Always refer to the Certificate of Analysis (COA) for lot-specific purity.
• Melting Point: Often cited in the range of 148-151°C. A sharp melting point within this range indicates good purity.
• Solubility: Generally soluble in common organic solvents like methanol and ethanol, with limited solubility in water. Specific solubility data can be critical for reaction design.
• Flash Point: Typically around 140.7°C, indicating moderate flammability.
• Boiling Point: Approximately 309°C at 760 mmHg (though decomposition may occur at higher temperatures).
• Density: Around 1.121 g/cm³.

Safe Handling and Storage Guidelines

Proper handling and storage are crucial for maintaining the integrity and safety of L-Proline Benzyl Ester Hydrochloride:

• Ventilation: Handle in a well-ventilated area, preferably under a fume hood, to avoid inhalation of dust or vapors.
• Personal Protective Equipment (PPE): Wear appropriate PPE, including safety goggles, chemical-resistant gloves (e.g., nitrile), and a lab coat. Respiratory protection may be necessary if dust generation is significant.
• Avoid Contact: Prevent contact with skin, eyes, and clothing. In case of contact, rinse immediately with plenty of water and seek medical attention if irritation persists.
• Storage Conditions: Store in a cool, dry, and well-ventilated place. Keep containers tightly closed to prevent moisture absorption, as it is a hydrochloride salt and can be hygroscopic. Protect from direct sunlight and incompatible materials.
• Incompatibilities: Avoid strong oxidizing agents and strong bases.
• Fire Safety: Keep away from heat, sparks, and open flames. Use non-sparking tools and ensure adequate fire suppression equipment is available.
