Chemical Structure

S-Methyl-L-Methionine Iodide CAS 3493-11-6 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including S-Methyl-L-Methionine Iodide.

S-Methyl-L-Methionine Iodide (CAS 3493-11-6), molecular formula C6H14NO2SI and molecular weight 291.14 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, S-Methyl-L-Methionine Iodide is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 291.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

CATO manufactures S-Methyl-L-Methionine Iodide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
