Chemical Structure

Maltopentaose CAS 34620-76-3 chemical structure

Description

Maltopentaose (CAS 34620-76-3) is a high-purity analytical reference standard with the molecular formula C30H52O26 and a molecular weight of 828.72 g/mol.

The molecular framework of Maltopentaose (C30H52O26) 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.
