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 Selenium(IV) bromide.
CATO supplies Selenium(IV) bromide (CAS 7789-65-3), a certified reference material (molecular formula Br4Se, MW 398.58 g/mol) for analytical method development and quality control.
Owing to bromine substitution, Selenium(IV) bromide is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 398.58 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 Selenium(IV) bromide 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.
