Chemical Structure

Ac-Tyr(tBu)-OH CAS 201292-99-1 chemical structure

Description

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

CATO supplies Ac-Tyr(tBu)-OH (CAS 201292-99-1), a certified reference material (molecular formula C15H21NO4, MW 279.33 g/mol) for analytical method development and quality control.

The molecular framework of Ac-Tyr(tBu)-OH (C15H21NO4) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), Ac-Tyr(tBu)-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.
