Chemical Structure
Description
CATO manufactures Fmoc-Ser-OtBu under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
CATO supplies Fmoc-Ser-OtBu (CAS 110797-35-8), a certified reference material (molecular formula C22H25NO5, MW 383.44 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, Fmoc-Ser-OtBu is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 383.44 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.
