Chemical Structure

4-Nitrophenyl β-D-cellopentaoside CAS 129411-63-8 chemical structure

Description

4-Nitrophenyl β-D-cellopentaoside (CAS 129411-63-8) is a high-purity analytical reference standard with the molecular formula C36H55NO28 and a molecular weight of 949.81 g/mol.

The molecular framework of 4-Nitrophenyl β-D-cellopentaoside (C36H55NO28) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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 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.
