Chemical Structure
Description
The occurrence of 1-Naphthyl α-D-galactopyranoside is closely related to a flavonoid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-Naphthyl α-D-galactopyranoside (CAS 65174-63-2) is a high-purity analytical reference standard with the molecular formula C16H18O6 and a molecular weight of 306.31 g/mol.
The molecular framework of 1-Naphthyl α-D-galactopyranoside (C16H18O6) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 1-Naphthyl α-D-galactopyranoside 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.
