Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 205.25 g/mol gives 1-tert-Butyl-4-(2-nitroethenyl)benzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1-tert-Butyl-4-(2-nitroethenyl)benzene (CAS 1056474-04-4), a certified reference material (molecular formula C12H15NO2, MW 205.25 g/mol) for analytical method development and quality control.
1-tert-Butyl-4-(2-nitroethenyl)benzene (C12H15NO2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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.
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.
As a certified reference material (CRM), 1-tert-Butyl-4-(2-nitroethenyl)benzene 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.
