Chemical Structure
Description
3-4-6-Tri-O-acetyl-2-deoxy-2-phthalimido-α-D-galactopyranosyl fluoride (CAS 177966-56-2) is a high-purity analytical reference standard with the molecular formula C20H20FNO9 and a molecular weight of 437.37 g/mol.
The molecular framework of 3-4-6-Tri-O-acetyl-2-deoxy-2-phthalimido-α-D-galactopyranosyl fluoride (C20H20FNO9) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
As a certified reference material (CRM), 3-4-6-Tri-O-acetyl-2-deoxy-2-phthalimido-α-D-galactopyranosyl fluoride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
