Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including L-Methionine-d3-N-FMOC (S-methyl-d3).
L-Methionine-d3-N-FMOC (S-methyl-d3) (CAS 502692-58-2) is a high-purity analytical reference standard with the molecular formula C20H18D3NO4S and a molecular weight of 374.47 g/mol.
Structurally, L-Methionine-d3-N-FMOC (S-methyl-d3) (C20H18D3NO4S) contains deuterium isotope labeling, a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.5, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 374.47 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), L-Methionine-d3-N-FMOC (S-methyl-d3) 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.
