92273-73-9 n-Butylzinc bromide, 0.5M in THF, packaged under Argon in resealable ChemSeal bottles MFCD00671997 CAS 92273-73-9

Description

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.

92273-73-9 n-Butylzinc bromide, 0.5M in THF, packaged under Argon in resealable ChemSeal bottles MFCD00671997 (CAS 92273-73-9), molecular formula C4H9BrZn and molecular weight 202.43 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 92273-73-9 n-Butylzinc bromide, 0.5M in THF, packaged under Argon in resealable ChemSeal bottles MFCD00671997 (C4H9BrZn) contains a salt form, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 202.43 g/mol, it falls into the medium-molecular-weight range. 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.
