Chemical Structure

(2E)-3-[4-(5-Pentylpyridin-2-yl)phenyl]acrylic acid CAS 1164538-14-0 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.

(2E)-3-[4-(5-Pentylpyridin-2-yl)phenyl]acrylic acid (CAS 1164538-14-0) is a high-purity analytical reference standard with the molecular formula C19H21NO2 and a molecular weight of 295.38 g/mol.

(2E)-3-[4-(5-Pentylpyridin-2-yl)phenyl]acrylic acid (C19H21NO2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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.
