Chemical Structure
Description
The molecular framework of 3-O-Benzyl-1,2-O-isopropylidene-b-L-lyxofuranose (C15H20O5) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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).
3-O-Benzyl-1,2-O-isopropylidene-b-L-lyxofuranose (CAS 34370-91-7), molecular formula C15H20O5 and molecular weight 280.32 g/mol, is a CATO reference standard with documented purity and traceability.
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-O-Benzyl-1,2-O-isopropylidene-b-L-lyxofuranose 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.
