L-Aspartic acid, N-[(9H-fluoren-9-ylmethoxy)carbonyl]-, 1-[2-carboxy-2-[[(1,1-dimethylethoxy)carbonyl]amino]-1-methylethyl] 4-(1,1-dimethylethyl) ester CAS 944283-33-4

Description

L-Aspartic acid, N-[(9H-fluoren-9-ylmethoxy)carbonyl]-, 1-[2-carboxy-2-[[(1,1-dimethylethoxy)carbonyl]amino]-1-methylethyl] 4-(1,1-dimethylethyl) ester (CAS 944283-33-4), molecular formula C32H40N2O10 and molecular weight 612.67 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, L-Aspartic acid, N-[(9H-fluoren-9-ylmethoxy)carbonyl]-, 1-[2-carboxy-2-[[(1,1-dimethylethoxy)carbonyl]amino]-1-methylethyl] 4-(1,1-dimethylethyl) ester is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 612.67 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), L-Aspartic acid, N-[(9H-fluoren-9-ylmethoxy)carbonyl]-, 1-[2-carboxy-2-[[(1,1-dimethylethoxy)carbonyl]amino]-1-methylethyl] 4-(1,1-dimethylethyl) ester 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.
