Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Methyl [2-(4-tert-butylphenoxy)ethyl]carbamate (CAS 690668-81-6), molecular formula C14H21NO3 and molecular weight 251.32 g/mol, is a CATO reference standard with documented purity and traceability.
Methyl [2-(4-tert-butylphenoxy)ethyl]carbamate (C14H21NO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), Methyl [2-(4-tert-butylphenoxy)ethyl]carbamate 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.
