Chemical Structure

Xylopentaose CAS 49694-20-4 chemical structure

Description

Xylopentaose (CAS 49694-20-4) is a high-purity analytical reference standard with the molecular formula C25H42O21 and a molecular weight of 678.59 g/mol.

The molecular framework of Xylopentaose (C25H42O21) 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).

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.
