Chemical Structure

ALUMINUM SULFATE HYDRATE ACS REAGENT GRADE CAS 16828-11-8 chemical structure

Description

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.

CATO supplies ALUMINUM SULFATE HYDRATE ACS REAGENT GRADE (CAS 16828-11-8), a certified reference material (molecular formula O4SAlH2O, MW 141.05 g/mol) for analytical method development and quality control.

The molecular framework of ALUMINUM SULFATE HYDRATE ACS REAGENT GRADE (O4SAlH2O) is characterized by a sulfone group. 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.

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.
