Chemical Structure

Potassium tetrachloroaluminate CAS 13821-13-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 207.88 g/mol gives Potassium tetrachloroaluminate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Potassium tetrachloroaluminate (CAS 13821-13-1), molecular formula AlCl4K and molecular weight 207.88 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Potassium tetrachloroaluminate (AlCl4K) is characterized by a salt form, chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO manufactures Potassium tetrachloroaluminate 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.
