Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 2-[2-(2,4-Dichloro-phenyl)-ethyl]-6-hydroxy-benzoic acid methyl ester (CAS 1171924-81-4), a certified reference material (molecular formula C16H14Cl2O3, MW 325.19 g/mol) for analytical method development and quality control.
Based on its molecular formula C16H14Cl2O3, 2-[2-(2,4-Dichloro-phenyl)-ethyl]-6-hydroxy-benzoic acid methyl ester contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 325.19 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
