Chemical Structure
Description
2-3-4-6-Tetra-O-benzoyl-α-D-galactopyranosyl trichloroacetimidate (CAS 138479-78-4) is a high-purity analytical reference standard with the molecular formula C36H28Cl3NO10 and a molecular weight of 740.97 g/mol.
Based on its molecular formula C36H28Cl3NO10, 2-3-4-6-Tetra-O-benzoyl-α-D-galactopyranosyl trichloroacetimidate contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 740.97 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
