Chemical Structure
Description
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.
CATO supplies 6-Amino-7-chloroquinoline-5,8-dione (CAS 18892-39-2), a certified reference material (molecular formula C59H90N8O12S, MW 1135.46 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 6-Amino-7-chloroquinoline-5,8-dione is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1135.46 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
