Chemical Structure

5,6-Dimethyl-[2,2'-bipyridine]-3,3'-diol CAS 666734-80-1 chemical structure

Description

CATO supplies 5,6-Dimethyl-[2,2'-bipyridine]-3,3'-diol (CAS 666734-80-1), a certified reference material (molecular formula C12H12N2O, MW 200.24 g/mol) for analytical method development and quality control.

Structurally, 5,6-Dimethyl-[2,2'-bipyridine]-3,3'-diol (C12H12N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 200.24 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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

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.
