Chemical Structure
Description
CATO supplies 5-Methyl-2-(4-pentylbenzoyl)pyridine (CAS 1187164-56-2), a certified reference material (molecular formula C18H21NO, MW 267.37 g/mol) for analytical method development and quality control.
5-Methyl-2-(4-pentylbenzoyl)pyridine (C18H21NO) contains a steroid core, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
