As a certified reference material (CRM), (S)-2,5-Dioxopyrrolidin-1-yl 2-((tert-butoxycarbonyl)amino)-6-((((2-chlorobenzyl)oxy)carbonyl)amino)hexanoate 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.
(S)-2,5-Dioxopyrrolidin-1-yl 2-((tert-butoxycarbonyl)amino)-6-((((2-chlorobenzyl)oxy)carbonyl)amino)hexanoate (CAS 66438-39-9) is a high-purity analytical reference standard with the molecular formula C23H30ClN3O8 and a molecular weight of 511.95 g/mol.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, (S)-2,5-Dioxopyrrolidin-1-yl 2-((tert-butoxycarbonyl)amino)-6-((((2-chlorobenzyl)oxy)carbonyl)amino)hexanoate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 511.95 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.
