Fmoc-<I>N</I>-Me-<SC>D</SC>-Phe-OH CAS 138775-05-0

Description

The occurrence of Fmoc-<I>N</I>-Me-<SC>D</SC>-Phe-OH is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Fmoc-<I>N</I>-Me-<SC>D</SC>-Phe-OH (CAS 138775-05-0), molecular formula C25H41NO4 and molecular weight 419.60 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Fmoc-<I>N</I>-Me-<SC>D</SC>-Phe-OH is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 419.60 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), Fmoc-<I>N</I>-Me-<SC>D</SC>-Phe-OH 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.
