4,4'-Di(heptadecan-9-yl)-2,2'-bipyridine CAS 258262-75-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4,4'-Di(heptadecan-9-yl)-2,2'-bipyridine.

4,4'-Di(heptadecan-9-yl)-2,2'-bipyridine (CAS 258262-75-8), molecular formula C44H76N2 and molecular weight 633.09 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 4,4'-Di(heptadecan-9-yl)-2,2'-bipyridine is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 633.09 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
