Chemical Structure

H-Val-pNA CAS 52084-13-6 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 237.25 g/mol gives H-Val-pNA distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies H-Val-pNA (CAS 52084-13-6), a certified reference material (molecular formula C11H15N3O3, MW 237.25 g/mol) for analytical method development and quality control.

H-Val-pNA (C11H15N3O3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.

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), H-Val-pNA 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.
