Chemical Structure
Description
The occurrence of n-Cyclopentyl-2-(4-formyl-2-methoxyphenoxy)acetamide is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
n-Cyclopentyl-2-(4-formyl-2-methoxyphenoxy)acetamide (CAS 765903-98-8) is a high-purity analytical reference standard with the molecular formula C15H19NO4 and a molecular weight of 277.32 g/mol.
n-Cyclopentyl-2-(4-formyl-2-methoxyphenoxy)acetamide (C15H19NO4) 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. 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.
