Each peak is a nominal mass with its abundance-weighted exact mass, as a percentage of the tallest, from IUPAC natural isotope abundances.

Computed from the structure with RDKit 2026.09 when this page was built, beside PubChem's own computed values from its record; where the two differ, both are shown.

Drug-likeness: Lipinski’s rule of five

  • Molecular weight ≤ 500: 146.15
  • log P ≤ 5 (Crippen): -1.34
  • H-bond donors ≤ 5: 3
  • H-bond acceptors ≤ 10: 3

Passes all four rules.

Safety

This chemical does not meet GHS hazard criteria for 98.8% (245 of 248) of all reports.[2]

Storage

  • Keep container tightly closed in a dry and well-ventilated place. Recommended storage temperature: -20 °C/L-Glutamine solution/[1]
  • Store at 25 °C (77 °F) with excursions allowed to 15 deg-30 °C (59 deg -86 °F).[1]

Incompatibilities

  • Strong oxidizing agents[1]
