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.

2,5,8,11,14,17,20,23,26,29,32,35,38,41,44,47,50,53-Octadecaoxapentapentacontan-55-ol (CAS 171286-86-5), molecular formula C37H76O19 and molecular weight 824.99 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2,5,8,11,14,17,20,23,26,29,32,35,38,41,44,47,50,53-Octadecaoxapentapentacontan-55-ol (C37H76O19) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 824.99 g/mol, it falls into the high-molecular-weight range.

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.
