Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Flavoxate EP Impurity A-d5 (Flavoxate USP Related Compound A-d5).
CATO supplies Flavoxate EP Impurity A-d5 (Flavoxate USP Related Compound A-d5) (CAS 1189883-79-1), a certified reference material (molecular formula C17H7D5O4, MW 285.31 g/mol) for analytical method development and quality control.
Based on its molecular formula C17H7D5O4, Flavoxate EP Impurity A-d5 (Flavoxate USP Related Compound A-d5) contains deuterium isotope labeling, a flavonoid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 285.31 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
