C16 Sphingomyelin-¹³C (d18:1/16:0-¹³C) is intended for use as an internal standard for the quantification of C16sphingomyelin by GC- or LC-MS. C16 Sphingomyelin is a naturally occurring sphingolipid. Levels of C16 sphingomyelin are elevated in the prefrontal cortex and cerebellum in a rat model of diabetes induced by streptozotocin (STZ; ), as well as in the liver in mouse models of Niemann-Pick type C1 disease. Plasma levels of C16 sphingomyelin are decreased in patients with prostate cancer. Model membranes containing C16 sphingomyelin, 1-palmitoyl-2-oleoyl-sn-glycero-3-PC (POPC; ), and cholesterol have been used in the study of lipid raft dynamics and membrane organization.

N-Palmitoyl-D-sphingomyelin-13C is a deuterated labeled N-Palmitoyl-D-sphingomyelin[1]. N-Palmitoyl-D-sphingomyelin (Sphingomyelin 16:0) (Compound SM-03) can be used for the synthesis of lipid nanoparticles[2].
