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-(4-Acetyl-2-methoxy-5-nitrophenoxy)-butanoic Acid Ethyl Ester.
4-(4-Acetyl-2-methoxy-5-nitrophenoxy)-butanoic Acid Ethyl Ester (CAS 1031702-80-3), molecular formula C15H19NO7 and molecular weight 325.31 g/mol, is a CATO reference standard with documented purity and traceability.
4-(4-Acetyl-2-methoxy-5-nitrophenoxy)-butanoic Acid Ethyl Ester (C15H19NO7) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. 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.
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.
