Chemical Structure

Fmoc-D-Val-OH CAS 84624-17-9 chemical structure

Description

Fmoc-D-Val-OH (CAS 84624-17-9), molecular formula C20H21NO4 and molecular weight 339.39 g/mol, is a CATO reference standard with documented purity and traceability.

Fmoc-D-Val-OH (C20H21NO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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-D-Val-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.
