Chemical Structure

L-Asparagine Monohydrate CAS 5794-13-8 chemical structure

Description

Owing to a carbohydrate-derived structure, an amide group, L-Asparagine Monohydrate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 150.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

CATO supplies L-Asparagine Monohydrate (CAS 5794-13-8), a certified reference material (molecular formula C4H8N2O3H2O, MW 150.13 g/mol) for analytical method development and quality control.

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), L-Asparagine Monohydrate 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.
