Description
As a certified reference material (CRM), 1-Isocyanato-4-pentylbenzene 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.
1-Isocyanato-4-pentylbenzene (CAS 121503-84-2), molecular formula C12H15NO and molecular weight 189.25 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C12H15NO, 1-Isocyanato-4-pentylbenzene contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 189.25 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.
