Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Diethyl 2-Chlorobenzylphosphonate (CAS 29074-98-4) is a high-purity analytical reference standard with the molecular formula C11H16ClO3P and a molecular weight of 262.67 g/mol.
Based on its molecular formula C11H16ClO3P, Diethyl 2-Chlorobenzylphosphonate contains a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 262.67 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.
As a certified reference material (CRM), Diethyl 2-Chlorobenzylphosphonate 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.
