Description

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.

Methyl (2S)-4-{[bis(4-methoxyphenyl)methyl]carbamoyl}-2-{[(9H-fluoren-9-ylmethoxy)carbonyl]amino}butanoate (CAS 1820581-56-3) is a high-purity analytical reference standard with the molecular formula C36H36N2O7 and a molecular weight of 608.68 g/mol.

The molecular framework of Methyl (2S)-4-{[bis(4-methoxyphenyl)methyl]carbamoyl}-2-{[(9H-fluoren-9-ylmethoxy)carbonyl]amino}butanoate (C36H36N2O7) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

As a certified reference material (CRM), Methyl (2S)-4-{[bis(4-methoxyphenyl)methyl]carbamoyl}-2-{[(9H-fluoren-9-ylmethoxy)carbonyl]amino}butanoate 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.
