Chemical Structure

IL-8ra (9-29) (N-1585.0500) CAS 188689-66-9 chemical structure

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.

CATO supplies IL-8ra (9-29) (N-1585.0500) (CAS 188689-66-9), a certified reference material (molecular formula C112H150N24O38S2, MW 2504.66 g/mol) for analytical method development and quality control.

Structurally, IL-8ra (9-29) (N-1585.0500) (C112H150N24O38S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 50.0, corresponding to approximately 50 ring(s) or double-bond equivalent(s). With a molecular weight of 2504.66 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.

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.
