Chemical Structure
Description
CATO supplies (2E)-4-Hydroxybut-2-en-1-yl N-(4-chlorophenyl)carbamate (CAS 57302-74-6), a certified reference material (molecular formula C11H12ClNO3, MW 241.67 g/mol) for analytical method development and quality control.
(2E)-4-Hydroxybut-2-en-1-yl N-(4-chlorophenyl)carbamate (C11H12ClNO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures (2E)-4-Hydroxybut-2-en-1-yl N-(4-chlorophenyl)carbamate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
