Chemical Structure

D-Arabinonic acid, calcium salt (2:1) CAS 22373-09-7 chemical structure

Description

The molecular framework of D-Arabinonic acid, calcium salt (2:1) (C5H9O6Ca) is characterized by a carbohydrate-derived structure. 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.

D-Arabinonic acid, calcium salt (2:1) (CAS 22373-09-7) is a high-purity analytical reference standard with the molecular formula C5H9O6Ca and a molecular weight of 205.20 g/mol.

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.

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.
