Chemical Structure
Description
tert-butyl N-[(1R,4S)-4-(benzyloxycarbonylamino)cyclopent-2-en-1-yl]carbamate (CAS 1931997-83-9), molecular formula C18H30N2O4 and molecular weight 338.44 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, tert-butyl N-[(1R,4S)-4-(benzyloxycarbonylamino)cyclopent-2-en-1-yl]carbamate (C18H30N2O4) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 338.44 g/mol, it falls into the moderately-high-molecular-weight range. 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.
As a certified reference material (CRM), tert-butyl N-[(1R,4S)-4-(benzyloxycarbonylamino)cyclopent-2-en-1-yl]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.
