Applications : Firmonertinib‑d₃ mesylate is a deuterium‑labelled version of the brain‑penetrant EGFR inhibitor Firmonertinib mesylate. Like the parent compound, it targets activating EGFR mutations and the T790M resistance mutation and is used in research on advanced NSCLC, particularly models harboring EGFR exon 20 insertions. The deuterium label supports applications in metabolic tracing and quantitative LC–MS analysis.

Storage : Keep container tightly closed under nitrogen or argon and refrigerate for long-term shelf life.

Caution : In case of contact with skin or eyes, rinse immediately with plenty of water and seek medical advice. Wear suitable protective clothing and gloves.
