HIV-1 env Protein gp120 (278-292) (strains BH10, BH8, HXB2, HXB3, PV22) (CAS 114991-28-5), molecular formula C73H126N26O18 and molecular weight 1655.97 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, HIV-1 env Protein gp120 (278-292) (strains BH10, BH8, HXB2, HXB3, PV22) (C73H126N26O18) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 24.0, corresponding to approximately 24 ring(s) or double-bond equivalent(s). With a molecular weight of 1655.97 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).
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.
