Description

The occurrence of Methyl 3-[4-(3-methylbutanamido)phenoxy]thiophene-2-carboxylate is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Methyl 3-[4-(3-methylbutanamido)phenoxy]thiophene-2-carboxylate (CAS 900019-27-4), molecular formula C17H19NO4S and molecular weight 333.40 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Methyl 3-[4-(3-methylbutanamido)phenoxy]thiophene-2-carboxylate (C17H19NO4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 333.40 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
