Chemical Structure
Description
Gadolinium(III) chloride hydrate (CAS 19423-81-5) is a high-purity analytical reference standard with the molecular formula Cl3GdH2O and a molecular weight of 281.62 g/mol.
The molecular framework of Gadolinium(III) chloride hydrate (Cl3GdH2O) is characterized by 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.
As a certified reference material (CRM), Gadolinium(III) chloride hydrate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
