Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 1404.24 g/mol gives Avilamycin distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Avilamycin (CAS 11051-71-1) is a high-purity analytical reference standard with the molecular formula C61H88Cl2O32 and a molecular weight of 1404.24 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system, Avilamycin is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1404.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
