Methyl (2R)-2-{[(9H-fluoren-9-ylmethoxy)carbonyl](methyl)amino}-4-methylpentanoate CAS 1820575-65-2 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Methyl (2R)-2-{[(9H-fluoren-9-ylmethoxy)carbonyl](methyl)amino}-4-methylpentanoate.

Methyl (2R)-2-{[(9H-fluoren-9-ylmethoxy)carbonyl](methyl)amino}-4-methylpentanoate (CAS 1820575-65-2) is a high-purity analytical reference standard with the molecular formula C23H27NO4 and a molecular weight of 381.46 g/mol.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, Methyl (2R)-2-{[(9H-fluoren-9-ylmethoxy)carbonyl](methyl)amino}-4-methylpentanoate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 381.46 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), Methyl (2R)-2-{[(9H-fluoren-9-ylmethoxy)carbonyl](methyl)amino}-4-methylpentanoate 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.
