Chemical Structure

Cyclo(-Met-Met) CAS 73037-51-1 chemical structure

Description

Cyclo(-Met-Met) (CAS 73037-51-1), molecular formula C10H18N2O2S2 and molecular weight 262.39 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, Cyclo(-Met-Met) is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 262.39 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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 Cyclo(-Met-Met) 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.
