Chemical Structure
Description
Based on its molecular formula C63H94N14O17S, Annexin A1 (1-11) (dephosphorylated) (human, bovine, chicken, porcine) (H-6676.0500) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 1351.57 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.
Annexin A1 (1-11) (dephosphorylated) (human, bovine, chicken, porcine) (H-6676.0500) (CAS 256447-08-2) is a high-purity analytical reference standard with the molecular formula C63H94N14O17S and a molecular weight of 1351.57 g/mol.
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.
