Chemical Structure
Description
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.
CATO supplies 2A,2B,2C,2D,2E,2F,6A,6B,6C,6D,6E,6F-Dodeca-O-methyl-α-Cyclodextrin (CAS 51166-72-4), a certified reference material (molecular formula C48H84O30, MW 1141.16 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, 2A,2B,2C,2D,2E,2F,6A,6B,6C,6D,6E,6F-Dodeca-O-methyl-α-Cyclodextrin is typically off-white to pale yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1141.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
