Chemical Structure
Description
The occurrence of 3,5-Dimethyl-2-(tributylstannyl)pyridine is closely related to a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3,5-Dimethyl-2-(tributylstannyl)pyridine (CAS 445373-10-4) is a high-purity analytical reference standard with the molecular formula C19H35NSn and a molecular weight of 396.20 g/mol.
Owing to a nitrile group, 3,5-Dimethyl-2-(tributylstannyl)pyridine is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 396.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
