Chemical Structure
Description
As a certified reference material (CRM), tert-Butyl (S)-2-(2-(tert-butoxy)-2-oxoethyl)aziridine-1-carboxylate 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.
tert-Butyl (S)-2-(2-(tert-butoxy)-2-oxoethyl)aziridine-1-carboxylate (CAS 1246961-44-3), molecular formula C13H23NO4 and molecular weight 257.33 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, tert-Butyl (S)-2-(2-(tert-butoxy)-2-oxoethyl)aziridine-1-carboxylate is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 257.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
