Chemical Structure

Boc-His-NHNH? CAS 42002-05-1 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 Boc-His-NHNH?.

CATO supplies Boc-His-NHNH? (CAS 42002-05-1), a certified reference material (molecular formula C11H19N5O3, MW 269.30 g/mol) for analytical method development and quality control.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Boc-His-NHNH? is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 269.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), Boc-His-NHNH? 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.
