Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4,4′-bipyridyl hydrate (CAS 123333-55-1), molecular formula C10H20N2H2O and molecular weight 186.30 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amide group, a hydroxyl group, an ether linkage, 4,4′-bipyridyl hydrate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 186.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), 4,4′-bipyridyl hydrate 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.
