1,2-Distearoyl-sn-glycerol is an internal standard for the isolation and characterization of molecular species of 1,2-diacyl-sn-glycerol (DAG).

2-Hydroxy-6-methoxybenzoic acid (6-Methoxysalicylic acid) may be employed as internal standard for the determination of acetylsalicylic acid (aspirin, ASA) and its major metabolite, salicylic acid (SA),and exhibits significant analgesic effects

2-Ethylbutyric acid is an internal standard that can be used in calibration methods for VFA analytical standards for feces.

C16 3'-sulfo Galactosylceramide (d18:1 16:0) inhibits retinal ganglion cell growth in vitro.C16 3'-sulfo Galactosylceramide (d18:1 16:0) has been used as an internal standard for quantifying C16 3'-sulfo Galactosylceramide (d18:1 16:0) in rat cerebellum and white matter isolated from patients with multiple sclerosis. reference for sulphides.

Sphingosine (d17:1) (C17 Sphingosine) is a 17-carbon sphingolipid found in human skin that can be phosphorylated by sphingomyelin kinase.Sphingosine C-17 can be used as an internal standard to perform spectroscopic analysis of sphingolipids.

Methyl Nonadecanoate (Nonadecanoic Acid methyl ester) is a fatty acid methyl ester

3-Methylcytidine (methosulfate), a derivative of cytidine, serves as an internal standard for HPLC and is recognized for its epigenetic modification in tRNA, although its cellular role remains unclear. Research has explored its utility as a cancer biomarker, with findings indicating a notable increase in the urine of breast cancer patients.
