Chemical Structure

<SC>DL</SC>-Methionine-<SUP>15</SUP>N CAS 104514-46-7 chemical structure

Description

<SC>DL</SC>-Methionine-<SUP>15</SUP>N (C5H11[15N]O2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

<SC>DL</SC>-Methionine-<SUP>15</SUP>N (CAS 104514-46-7), molecular formula C5H11[15N]O2S and molecular weight 150.20 g/mol, is a CATO reference standard with documented purity and traceability.

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), <SC>DL</SC>-Methionine-<SUP>15</SUP>N 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.
