Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

C04977SRJ5 8AD8CNQ956 2304-80-5 N-Stearoyl dihydrosphingosine UNII-8AD8CNQ956 Octadecanamide, N-((1S,2R)-2-hydroxy-1-(hydroxymethyl)heptadecyl)- Octadecanamide, N-(2-hydroxy-1-(hydroxymethyl)heptadecyl)-, D-erythro- Octadecanamide, N-(2-hydroxy-1-(hydroxymethyl)heptadecyl)-, (R-(R*,S*))- (2S,3R)-2-(Octadecanoylamino)octadecane-1,3-diol UNII-C04977SRJ5 (CAS 2304-80-5), molecular formula C36H73NO3 and molecular weight 567.97 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, C04977SRJ5 8AD8CNQ956 2304-80-5 N-Stearoyl dihydrosphingosine UNII-8AD8CNQ956 Octadecanamide, N-((1S,2R)-2-hydroxy-1-(hydroxymethyl)heptadecyl)- Octadecanamide, N-(2-hydroxy-1-(hydroxymethyl)heptadecyl)-, D-erythro- Octadecanamide, N-(2-hydroxy-1-(hydroxymethyl)heptadecyl)-, (R-(R*,S*))- (2S,3R)-2-(Octadecanoylamino)octadecane-1,3-diol UNII-C04977SRJ5 (C36H73NO3) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 567.97 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
