Chemical Structure

18:1 Sphingomyelin/SM (d18:1/18:1(9Z)) CAS 108392-10-5 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 18:1 Sphingomyelin/SM (d18:1/18:1(9Z)).

18:1 Sphingomyelin/SM (d18:1/18:1(9Z)) (CAS 108392-10-5) is a high-purity analytical reference standard with the molecular formula C41H81N2O6P and a molecular weight of 729.07 g/mol.

Structurally, 18:1 Sphingomyelin/SM (d18:1/18:1(9Z)) (C41H81N2O6P) contains an amide group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.5, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 729.07 g/mol, it falls into the high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
