Chemical Structure

(R)-2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-5-((1-(4,4-dimethyl-2,6-dioxocyclohexylidene)-3-methylbutyl)amino)pentanoic acid CAS 1272754-86-5 chemical structure

Description

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, (R)-2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-5-((1-(4,4-dimethyl-2,6-dioxocyclohexylidene)-3-methylbutyl)amino)pentanoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 560.68 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).

(R)-2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-5-((1-(4,4-dimethyl-2,6-dioxocyclohexylidene)-3-methylbutyl)amino)pentanoic acid (CAS 1272754-86-5) is a high-purity analytical reference standard with the molecular formula C33H40N2O6 and a molecular weight of 560.68 g/mol.

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), (R)-2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-5-((1-(4,4-dimethyl-2,6-dioxocyclohexylidene)-3-methylbutyl)amino)pentanoic acid 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.
