Description
CATO supplies 3,5-Dimethyl-benzofuran-2-carbonyl chloride (CAS 16817-33-7), a certified reference material (molecular formula C11H9ClO2, MW 208.64 g/mol) for analytical method development and quality control.
Based on its molecular formula C11H9ClO2, 3,5-Dimethyl-benzofuran-2-carbonyl chloride contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 208.64 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 3,5-Dimethyl-benzofuran-2-carbonyl chloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
