Chemical Structure

Potassium L-Aspartate hemiHydrate CAS 7259-25-8 chemical structure

Description

The molecular framework of Potassium L-Aspartate hemiHydrate (C4H5NO4KH2OH) is characterized by a carbohydrate-derived structure, an amide group. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Potassium L-Aspartate hemiHydrate (CAS 7259-25-8) is a high-purity analytical reference standard with the molecular formula C4H5NO4KH2OH and a molecular weight of 189.21 g/mol.

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 L-Aspartate hemiHydrate 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.
