The occurrence of 1-2-3-4-6-Penta-O-benzoyl-α-D-galactopyranose is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1-2-3-4-6-Penta-O-benzoyl-α-D-galactopyranose (CAS 41545-55-5), a certified reference material (molecular formula C41H32O11, MW 700.69 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, 1-2-3-4-6-Penta-O-benzoyl-α-D-galactopyranose is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 700.69 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
