Chemical Structure

Ac-DL-Phe-β-naphthyl ester CAS 20874-31-1 chemical structure

Description

As a certified reference material (CRM), Ac-DL-Phe-β-naphthyl ester 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.

CATO supplies Ac-DL-Phe-β-naphthyl ester (CAS 20874-31-1), a certified reference material (molecular formula C21H19NO3, MW 333.38 g/mol) for analytical method development and quality control.

Ac-DL-Phe-β-naphthyl ester (C21H19NO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
