Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Methyl 2-3-6-tri-O-benzoyl-4-O-trifluoromethanesulfonyl-α-D-galactopyranoside (CAS 79580-70-4) is a high-purity analytical reference standard with the molecular formula C29H25F3O11S and a molecular weight of 638.56 g/mol.
Structurally, Methyl 2-3-6-tri-O-benzoyl-4-O-trifluoromethanesulfonyl-α-D-galactopyranoside (C29H25F3O11S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 638.56 g/mol, it falls into the high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
