Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(((tert-Butoxycarbonyl)amino)methyl)-6-fluoro-2,2-dimethylchroman-8-carboxylic acid.
CATO supplies 4-(((tert-Butoxycarbonyl)amino)methyl)-6-fluoro-2,2-dimethylchroman-8-carboxylic acid (CAS 1956332-03-8), a certified reference material (molecular formula C18H24FNO5, MW 353.39 g/mol) for analytical method development and quality control.
4-(((tert-Butoxycarbonyl)amino)methyl)-6-fluoro-2,2-dimethylchroman-8-carboxylic acid (C18H24FNO5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. 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. 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.
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.
