Overview and Chemical Properties

Cyclocarboxypropyloleic acid (SKU: C1022915) is a specialty lipid reagent characterized by the combination of a cyclic carboxypropyl functional group with an oleoyl (C18:1) fatty acid backbone. This dual functionality confers amphiphilic character, enabling its use in interfacial chemistry, lipid membrane studies, and as a precursor in the synthesis of more complex lipid conjugates.

The carboxylic acid groups present in the molecule allow further derivatization via esterification, amidation, or salt formation, expanding its utility across multiple research domains including biomaterial science and green surfactant development.

Note: Detailed physicochemical data (exact molecular weight, melting point, LogP, pKa) should be confirmed against the current Certificate of Analysis (CoA) and Safety Data Sheet (SDS) available from Aladdin Scientific for lot-specific values.

Safety and Handling

As with all specialty fatty acid derivatives, appropriate personal protective equipment (PPE) must be used when handling Cyclocarboxypropyloleic acid. At minimum, wear chemical-resistant gloves, a laboratory coat, and safety goggles.

• Ventilation: Work in a fume hood or well-ventilated area, particularly when using volatile co-solvents such as chloroform or dichloromethane.
• Storage: Keep the compound sealed under an inert gas (nitrogen or argon) at 2–8 °C, away from light and moisture to prevent hydrolysis or oxidation of the unsaturated chain.
• Disposal: Dispose of waste material in accordance with local regulations for organic chemical waste. Do not pour organic solvents down the drain.
• First Aid: In case of skin or eye contact, rinse immediately with copious water and seek medical advice. Refer to the current SDS for complete hazard information.

Review flag: Specific GHS hazard classifications and first-aid measures must be confirmed from the official SDS for lot C1022915 before use.

Solution Preparation Protocol

The following protocol describes a general approach to preparing a stock solution of Cyclocarboxypropyloleic acid. Actual solubility must be verified experimentally for each lot.

1. Equilibrate to room temperature: Allow the sealed vial to warm to room temperature before opening to prevent moisture condensation on the compound.
2. Select solvent: Ethanol, DMSO, or chloroform are recommended as primary solvents based on the amphiphilic nature of the compound. For aqueous applications, prepare a concentrated stock in DMSO and dilute into the aqueous buffer immediately before use (final DMSO concentration ≤ 0.1% v/v is preferred).
3. Weigh accurately: Tare a clean, dry microcentrifuge tube and transfer the desired mass of Cyclocarboxypropyloleic acid using a micro-spatula.
4. Add solvent: Add the appropriate volume of solvent to achieve the target concentration (e.g., 10 mM stock). Vortex gently for 30–60 seconds.
5. Sonication (if needed): If the compound does not dissolve completely, sonicate in a water bath sonicator at room temperature for 5–10 minutes.
6. Filter (optional): For sensitive assays, pass the solution through a 0.22 µm PTFE syringe filter.
7. Aliquot and store: Divide the stock into single-use aliquots, seal under nitrogen, and store at –20 °C. Avoid repeated freeze-thaw cycles.

Note: Specific solubility values (mg/mL) have not been confirmed in the source material and should be validated by the end user.

Representative Laboratory Applications

Cyclocarboxypropyloleic acid is applicable across several research domains due to its bifunctional structure:

• Surfactant and emulsification studies: The amphiphilic character of this compound makes it a candidate for evaluating critical micelle concentration (CMC), emulsion stability, and interfacial tension reduction in model systems.
• Lipid conjugate synthesis: The reactive carboxylic acid groups can be coupled to amines (peptides, proteins, polymers) via standard carbodiimide (EDC/NHS) coupling chemistry to generate lipid–biomolecule conjugates.
• Membrane biophysics: As a fatty acid derivative with an unsaturated chain, it may be incorporated into liposomal formulations or used to study membrane fluidity and lipid–protein interactions.
• Material science: Potential use as a bio-based plasticizer or compatibilizer in polymer systems, leveraging the cyclic ring structure for improved thermal stability.

Disclaimer: These applications are proposed based on structural analogy with related fatty acid derivatives. Users should validate fitness-for-purpose in their specific experimental systems. No peer-reviewed application data specific to this compound was available in the source material.

Quality Control and Verification

To ensure experimental reproducibility when working with Cyclocarboxypropyloleic acid, the following QC checks are recommended:

• Identity confirmation: Verify compound identity by ¹H NMR or LC-MS prior to use in critical experiments. Compare to the CoA spectrum where available.
• Purity assessment: Use reverse-phase HPLC (C18 column, acetonitrile/water gradient with 0.1% formic acid) to assess purity. Accept lots with purity ≥ 95% for quantitative studies.
• Oxidation check: Fatty acid derivatives with unsaturated chains are susceptible to peroxidation. Check for rancidity or color change before use; discard discolored material.
• Concentration verification: For critical assays, verify stock concentration by a complementary analytical method (e.g., fatty acid quantification kit or UV absorbance if a chromophore is present).
