Answer

Thank you for contacting Abcam.

We currently run our HPLC at 25°C and we do not believe that this should cause issue with the compound. Although we do not have experience with preparing samples in phosphate buffer, as this seems to be the main difference between our preparation and yours it may be possible that this has caused issue with the HPLC trace.
Please do not hesitate to contact me should you have any further questions.

Answer

Thank you for contacting Abcam.

I have been in contact with the lab about the issue you were having with ab120432, Tertiapin Q. Please see their response below:

Following your question, Tertiapin Q has been re-submitted for quality control (QC) and has passed this. Please find attached the HPLC trace for this. In this trace there was one peak observed. We believe that you may be seeing two peaks due to partial ionisation at the pH of your buffer. Is it possible to modify your HPLC conditions to match our analysis? This may prevent the two peaks that you have previously seen.

Please let me know if there is anything else I can help you with.
