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 (1S,1'S)-1,1'-(pyridine-2,6-diyl)bis(ethan-1-ol).
(1S,1'S)-1,1'-(pyridine-2,6-diyl)bis(ethan-1-ol) (CAS 143329-85-5) is a high-purity analytical reference standard with the molecular formula C9H13NO2 and a molecular weight of 167.21 g/mol.
(1S,1'S)-1,1'-(pyridine-2,6-diyl)bis(ethan-1-ol) (C9H13NO2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
