Chemical Structure

Annexin A1 (1-25) (dephosphorylated) (human) CAS 151988-33-9 chemical structure

Description

The occurrence of Annexin A1 (1-25) (dephosphorylated) (human) is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Annexin A1 (1-25) (dephosphorylated) (human) (CAS 151988-33-9), a certified reference material (molecular formula C141H210N32O44S, MW 3089.47 g/mol) for analytical method development and quality control.

Structurally, Annexin A1 (1-25) (dephosphorylated) (human) (C141H210N32O44S) 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 53.0, corresponding to approximately 53 ring(s) or double-bond equivalent(s). With a molecular weight of 3089.47 g/mol, it falls into the high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
