Erbium(III) chloride CAS 10138-41-7

Description

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

Erbium(III) chloride (CAS 10138-41-7) is a high-purity analytical reference standard with the molecular formula Cl3Er and a molecular weight of 273.62 g/mol.

Owing to chlorine substitution, Erbium(III) chloride is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 273.62 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.

CATO manufactures Erbium(III) chloride 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.
