Biological Activity
All-cis-4,7,10,13,16-Docosapentaenoic acid ethyl ester (all-cis-4,7,10,13,16-DPA ethyl ester) is a derivative of docosapentaenoic acid (DPA), an omega-3 fatty acid prevalent in fish oils. This ethyl ester form is commonly included in dietary supplements formulations to enhance omega-3 fatty acid intake.
Safety & Regulatory
For Research Use Only (RUO). Not for therapeutic, diagnostic, or clinical use. Wear appropriate PPE and consult the Safety Data Sheet (SDS) prior to handling.
Use a bath-type ultrasonic cleaner at standard cleaning frequency (37–40 kHz). Bath sonication is gentler than a probe sonicator and avoids sample overheating. Sonicate in 5–10 second intervals, checking solubility between pulses, for no more than 2–3 minutes total. Warm the bath to 37 °C if solubility remains poor.
Use a bath-type ultrasonic cleaner rather than a high-intensity ultrasonic disruptor. Bath sonicators provide gentle, uniform agitation appropriate for dissolving solid compounds without generating cavitation damage or excessive heat. Ensure the solvent tube is fully submerged and use short sonication pulses of 5–10 seconds.
