Chemical Structure

Osmium(III) chloride trihydrate CAS 135296-80-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Osmium(III) chloride trihydrate.

Osmium(III) chloride trihydrate (CAS 135296-80-9), molecular formula Cl3OsH2O and molecular weight 314.60 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Osmium(III) chloride trihydrate (Cl3OsH2O) 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), Osmium(III) chloride trihydrate 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.
