N-Pivaloyl-L-tyrosine CAS 33019-85-1

Description

Compared with other compounds in its class, the molecular weight of 265.30 g/mol gives N-Pivaloyl-L-tyrosine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

N-Pivaloyl-L-tyrosine (CAS 33019-85-1) is a high-purity analytical reference standard with the molecular formula C14H19NO4 and a molecular weight of 265.30 g/mol.

The molecular framework of N-Pivaloyl-L-tyrosine (C14H19NO4) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

As a certified reference material (CRM), N-Pivaloyl-L-tyrosine 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.
