Chemical Structure

H-D-Met(O2)-OH CAS 41486-92-4 chemical structure

Description

H-D-Met(O2)-OH (CAS 41486-92-4) is a high-purity analytical reference standard with the molecular formula C5H11NO4S and a molecular weight of 181.21 g/mol.

Structurally, H-D-Met(O2)-OH (C5H11NO4S) contains a carbohydrate-derived structure, an amide group, a sulfone group. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 181.21 g/mol, it falls into the medium-molecular-weight range. 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-D-Met(O2)-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.
