Hexadecanal-d5 (Synonyms: 1-Hexadecanal-d5, Palmitaldehyde-d5)

Hexadecanal-d₅ contains five deuterium atoms at the 15, 15', 16, 16 and 16 positions. It is intended for use as an internal standard for the quantification of hexadecanal by GC- or LC-mass spectrometry. Sphingosine-1-phosphate (S1P) is a potent bioactive phospholipid that exhibits a broad spectrum of biological activities including cell proliferation, survival, migration, cytoskeletal organization, and morphogenesis.¹ Hexadecanal is the 16-carbon aldehyde analog of palmitic acid. It is produced from the irreversible cleavage of S1P by S1P lyase 1 and is a major component of plasmalogen.^2,3
