Chemical Structure
Description
CATO supplies 1-Chloro-3,5-difluoro-2-methyl-4-propoxybenzene (CAS 1881330-42-2), a certified reference material (molecular formula C10H11ClF2O, MW 220.64 g/mol) for analytical method development and quality control.
Based on its molecular formula C10H11ClF2O, 1-Chloro-3,5-difluoro-2-methyl-4-propoxybenzene contains a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 220.64 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
