Key Identifiers and General Information

• Product Name: 1-Cyclohexene-1-carboxylic Acid
• CAS Number: 636-82-8
• Molecular Formula: C7H10O2
• Molecular Weight: 126.15 g/mol
• Synonyms: 1-cyclohexenecarboxylic acid, 3,4,5,6-tetrahydrobenzoic acid, cyclohex-1-ene-1-carboxylic acid, among others. These synonyms help in cross-referencing and searching for the compound from various suppliers.

Physical and Chemical Properties

• Appearance: Typically described as a clear, colorless liquid. This visual characteristic is an important initial quality check for buyers.
• Purity: Manufacturers commonly supply this compound at a minimum purity of 97%. Higher purity grades may be available upon request for specialized applications.
• Melting Point: Reported values are around 30-39°C. This indicates it is a solid at room temperature if cooled below this range, but often handled as a liquid given typical ambient conditions.
• Boiling Point: Approximately 133-135°C at 14 mmHg. This is a key parameter for distillation and purification processes.
• Flash Point: Greater than 110°C (230°F). This suggests a relatively low flammability hazard under normal handling conditions.
• Density: Around 1.101 g/mL at 25°C. This property is useful for volumetric calculations in manufacturing.
• Solubility: Soluble in water (approximately 0.7 g/L at 20°C). It is generally soluble in common organic solvents, which is beneficial for its use in synthesis.

Handling and Storage Recommendations

As a chemical intermediate, proper handling and storage are essential for maintaining its quality and ensuring safety:

• Storage Condition: Store in a cool, dry, and well-ventilated area, away from incompatible substances. Containers should be kept tightly closed to prevent moisture absorption and contamination.
• Incompatibilities: It is generally incompatible with strong bases and oxidizing agents. Always consult the Safety Data Sheet (SDS) for detailed compatibility information.
• Safety Precautions: Although typically handled as a liquid, it's important to note its potential for skin and eye irritation. Wear appropriate personal protective equipment (PPE), including gloves, safety glasses, and lab coats when handling.
