557-68-6 Bromoiodomethane, stabilized with copper CH2BrI X3346 CAS 557-68-6

Description

Compared with other compounds in its class, the molecular weight of 220.84 g/mol gives 557-68-6 Bromoiodomethane, stabilized with copper CH2BrI X3346 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

557-68-6 Bromoiodomethane, stabilized with copper CH2BrI X3346 (CAS 557-68-6), molecular formula CH2BrI and molecular weight 220.84 g/mol, is a CATO reference standard with documented purity and traceability.

557-68-6 Bromoiodomethane, stabilized with copper CH2BrI X3346 (CH2BrI) contains bromine/iodine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
