Chemical Structure
Description
The occurrence of <SC>L</SC>-Methionine-<SUP>15</SUP>N is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
<SC>L</SC>-Methionine-<SUP>15</SUP>N (CAS 82572-25-6), molecular formula C5H11[15N]O2S and molecular weight 150.20 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, <SC>L</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 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 150.20 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
