Monensin Methyl Ester CAS 28636-21-7 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

Monensin Methyl Ester (CAS 28636-21-7), molecular formula C37H64O11 and molecular weight 684.90 g/mol, is a CATO reference standard with documented purity and traceability.

Monensin Methyl Ester (C37H64O11) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
