Chemical Structure

Xylotetrose CAS 22416-58-6 chemical structure

Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

Xylotetrose (CAS 22416-58-6), molecular formula C20H34O17 and molecular weight 546.47 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C20H34O17, Xylotetrose contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 546.47 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO manufactures Xylotetrose under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
