Chemical Structure
Description
Bis-[N-[2,6-Bis(1-methylethyl)phenyl]-α-(2-methylphenyl)-6-(1-naphthalenyl-κC2)-2-pyridinemethanaminato(2-)-κN1,κN2]dimethylhafnium (CAS 524680-42-0), molecular formula C37H40HfN2 and molecular weight 691.22 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, Bis-[N-[2,6-Bis(1-methylethyl)phenyl]-α-(2-methylphenyl)-6-(1-naphthalenyl-κC2)-2-pyridinemethanaminato(2-)-κN1,κN2]dimethylhafnium is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 691.22 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.
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.
