Chemical Structure
Description
The occurrence of 2-Fluoro-3-methyl-5-(tributylstannyl)pyridine 2754AE 405556-98-1 C18H32FNSn is closely related to fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Fluoro-3-methyl-5-(tributylstannyl)pyridine 2754AE 405556-98-1 C18H32FNSn (CAS 405556-98-1) is a high-purity analytical reference standard with the molecular formula C18H38FNSn and a molecular weight of 406.21 g/mol.
Owing to fluorine substitution, 2-Fluoro-3-methyl-5-(tributylstannyl)pyridine 2754AE 405556-98-1 C18H32FNSn is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 406.21 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.
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.
