Chemical Structure

H-Arg-Met-OH CAS 45243-23-0 chemical structure

Description

As a certified reference material (CRM), H-Arg-Met-OH 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.

H-Arg-Met-OH (CAS 45243-23-0) is a high-purity analytical reference standard with the molecular formula C11H23N5O3S and a molecular weight of 305.40 g/mol.

Structurally, H-Arg-Met-OH (C11H23N5O3S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 305.40 g/mol, it falls into the moderately-high-molecular-weight range. 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.
