Description
Benzyl 3-(4-chlorophenyl)acrylate (CAS 133793-08-5), molecular formula C16H13ClO2 and molecular weight 272.73 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C16H13ClO2, Benzyl 3-(4-chlorophenyl)acrylate 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 272.73 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.
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), Benzyl 3-(4-chlorophenyl)acrylate 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.
