Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 715.91 g/mol gives 10,11-Anhydroerythromycin A distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 10,11-Anhydroerythromycin A (CAS 40554-78-7), a certified reference material (molecular formula C37H65NO12, MW 715.91 g/mol) for analytical method development and quality control.
Structurally, 10,11-Anhydroerythromycin A (C37H65NO12) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 715.91 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.
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.
