(2S,3S,4R)-2-Azido-1,3,4-octadecanetriol CAS 117168-59-9 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 (2S,3S,4R)-2-Azido-1,3,4-octadecanetriol.

(2S,3S,4R)-2-Azido-1,3,4-octadecanetriol (CAS 117168-59-9), molecular formula C18H37N3O3 and molecular weight 343.50 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C18H37N3O3, (2S,3S,4R)-2-Azido-1,3,4-octadecanetriol contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 343.50 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

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.
