Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6-chloro-2(1H)-Quinolinone, potassium salt (1:1).
6-chloro-2(1H)-Quinolinone, potassium salt (1:1) (CAS 92449-39-3), molecular formula C9H5ClNOK and molecular weight 217.69 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a salt form, a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 6-chloro-2(1H)-Quinolinone, potassium salt (1:1) is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 217.69 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.
