Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 3-Cyclopropoxy-4-ethyl-5-methylpyridine is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 177.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
3-Cyclopropoxy-4-ethyl-5-methylpyridine (CAS 1243318-47-9) is a high-purity analytical reference standard with the molecular formula C11H15NO and a molecular weight of 177.24 g/mol.
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.
