Chemical Structure
Description
2,3-Di(pyridin-3-yl)butane-2,3-diol (CAS 4989-59-7) is a high-purity analytical reference standard with the molecular formula C8H10N2O3 and a molecular weight of 182.18 g/mol.
Structurally, 2,3-Di(pyridin-3-yl)butane-2,3-diol (C8H10N2O3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 182.18 g/mol, it falls into the medium-molecular-weight range. 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.
As a certified reference material (CRM), 2,3-Di(pyridin-3-yl)butane-2,3-diol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
