Description
Benzyl 2-[[(2S)-2-[[(2R)-2-[[2-(tert-butoxycarbonylamino)acetyl]amino]-3-phenyl-propanoyl]amino]-4-methyl-pentanoyl]amino]acetate (CAS 2227198-99-2) is a high-purity analytical reference standard with the molecular formula C31H42N4O7 and a molecular weight of 582.69 g/mol.
Benzyl 2-[[(2S)-2-[[(2R)-2-[[2-(tert-butoxycarbonylamino)acetyl]amino]-3-phenyl-propanoyl]amino]-4-methyl-pentanoyl]amino]acetate (C31H42N4O7) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), Benzyl 2-[[(2S)-2-[[(2R)-2-[[2-(tert-butoxycarbonylamino)acetyl]amino]-3-phenyl-propanoyl]amino]-4-methyl-pentanoyl]amino]acetate 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.
