Applicazioni

4-Hydroxy-3,5-dimethoxycinnamic acid is a commonly used matrix in MALDI mass spectrometry. It is a useful matrix for a wide variety of peptides and proteins. It serves well as a matrix for MALDI due to its ability to absorb laser radiation and to also donate protons (H+) to the analyte of interest.

Note

Store in cool dry place in tightly closed container. With good ventilation. Store away from oxidizing agent.
