Chemical Structure

Ac-Thr-Leu-Asn-Phe-OH CAS 137372-00-0 chemical structure

Description

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.

Ac-Thr-Leu-Asn-Phe-OH (CAS 137372-00-0), molecular formula C25H37N5O8 and molecular weight 535.59 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, Ac-Thr-Leu-Asn-Phe-OH is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 535.59 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).

As a certified reference material (CRM), Ac-Thr-Leu-Asn-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.
