Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Bz-Tyr-4-Abz-OH · sodium salt.
Bz-Tyr-4-Abz-OH · sodium salt (CAS 41748-47-4), molecular formula C23H19N2O5Na and molecular weight 426.40 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Bz-Tyr-4-Abz-OH · sodium salt (C23H19N2O5Na) is characterized by a flavonoid core, 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. 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.
As a certified reference material (CRM), Bz-Tyr-4-Abz-OH · sodium salt 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.
