Chemical Structure
Description
CATO supplies tert-Butyl ((R)-1-((S)-2-amino-3-methylbutanoyl)pyrrolidin-3-yl)(isopropyl)carbamate (CAS 1401666-07-6), a certified reference material (molecular formula C17H33N3O3, MW 327.46 g/mol) for analytical method development and quality control.
Structurally, tert-Butyl ((R)-1-((S)-2-amino-3-methylbutanoyl)pyrrolidin-3-yl)(isopropyl)carbamate (C17H33N3O3) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 327.46 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 ((R)-1-((S)-2-amino-3-methylbutanoyl)pyrrolidin-3-yl)(isopropyl)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.
