Chemical Structure
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.
6-(((Tert-butyldimethylsilyl)oxy)methyl)-2,3-dimethoxypyridine (CAS 1138443-87-4) is a high-purity analytical reference standard with the molecular formula C14H25NO3Si and a molecular weight of 283.44 g/mol.
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, 6-(((Tert-butyldimethylsilyl)oxy)methyl)-2,3-dimethoxypyridine is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 283.44 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
