Chemical Structure

H-Trp-NH? · HCl CAS 5022-65-1 chemical structure

Description

CATO supplies H-Trp-NH? · HCl (CAS 5022-65-1), a certified reference material (molecular formula C11H13N3OHCl, MW 239.70 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, H-Trp-NH? · HCl is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 239.70 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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-Trp-NH? · HCl 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.
