1-Bromo-4-fluoronaphthalene 21-Acetoxy-9-fluoro-11b,17-dihydroxypregna-1,4-diene-3,20-dione 341-41-3 CAS 341-41-3

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.

1-Bromo-4-fluoronaphthalene 21-Acetoxy-9-fluoro-11b,17-dihydroxypregna-1,4-diene-3,20-dione 341-41-3 (CAS 341-41-3) is a high-purity analytical reference standard with the molecular formula C10H16BrF and a molecular weight of 235.14 g/mol.

Based on its molecular formula C10H16BrF, 1-Bromo-4-fluoronaphthalene 21-Acetoxy-9-fluoro-11b,17-dihydroxypregna-1,4-diene-3,20-dione 341-41-3 contains fluorine/bromine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 235.14 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
