Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 475662-40-9 N-tricosanoylsphing-4-enine-1-phosphocholine C23 Sphingomyelin N-(Tricosanoyl)-sphing-4-enine-1-phosphocholine SM(d18:1/23:0) Milk SM Sphingomyelin (Milk, Bovine) sphingomyelin-milk (2S,3R,4E)-3-hydroxy-2-(tricosanoylamino)octadec-4-en-1-yl 2-(trimethylazaniumyl)ethyl phosphate milk sphingomyelin CHEBI:83880.

475662-40-9 N-tricosanoylsphing-4-enine-1-phosphocholine C23 Sphingomyelin N-(Tricosanoyl)-sphing-4-enine-1-phosphocholine SM(d18:1/23:0) Milk SM Sphingomyelin (Milk, Bovine) sphingomyelin-milk (2S,3R,4E)-3-hydroxy-2-(tricosanoylamino)octadec-4-en-1-yl 2-(trimethylazaniumyl)ethyl phosphate milk sphingomyelin CHEBI:83880 (CAS 475662-40-9) is a high-purity analytical reference standard with the molecular formula C46H93N2O6P and a molecular weight of 801.21 g/mol.

Owing to an amide group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, 475662-40-9 N-tricosanoylsphing-4-enine-1-phosphocholine C23 Sphingomyelin N-(Tricosanoyl)-sphing-4-enine-1-phosphocholine SM(d18:1/23:0) Milk SM Sphingomyelin (Milk, Bovine) sphingomyelin-milk (2S,3R,4E)-3-hydroxy-2-(tricosanoylamino)octadec-4-en-1-yl 2-(trimethylazaniumyl)ethyl phosphate milk sphingomyelin CHEBI:83880 is typically white to off-white amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 801.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
