Chemical Structure

Aluminum silicate CAS 12428-46-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 258.16 g/mol gives Aluminum silicate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Aluminum silicate (CAS 12428-46-5) is a high-purity analytical reference standard with the molecular formula O5Si2H4Al2O4 and a molecular weight of 258.16 g/mol.

The molecular framework of Aluminum silicate (O5Si2H4Al2O4) is characterized by an inorganic composition. 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.

CATO manufactures Aluminum silicate 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.
