Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
CATO supplies 2-(2-(4-((7-Chloroquinoxalin-2-yl)oxy)phenoxy)propanamido)acetic acid (CAS 643753-06-4), a certified reference material (molecular formula C19H16ClN3O5, MW 401.80 g/mol) for analytical method development and quality control.
2-(2-(4-((7-Chloroquinoxalin-2-yl)oxy)phenoxy)propanamido)acetic acid (C19H16ClN3O5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
