Compared with other compounds in its class, the molecular weight of 256.72 g/mol gives Samarium(III) chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Samarium(III) chloride (CAS 10361-82-7), molecular formula Cl3Sm and molecular weight 256.72 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to chlorine substitution, Samarium(III) chloride is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 256.72 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
As a certified reference material (CRM), Samarium(III) chloride 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.
