Chemical Structure

4-(tert-Butyl)-5-cyclopropoxy-2-methylpyridine CAS 1243329-44-3 chemical structure

Description

4-(tert-Butyl)-5-cyclopropoxy-2-methylpyridine (C13H19NO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

4-(tert-Butyl)-5-cyclopropoxy-2-methylpyridine (CAS 1243329-44-3), molecular formula C13H19NO and molecular weight 205.30 g/mol, is a CATO reference standard with documented purity and traceability.

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.
