Ethyl 2-(2-allyl-6-methoxy-1-oxo-1,2,3,4-tetrahydronaphthalen-2-yl)acetate CAS 2219339-66-7 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 Ethyl 2-(2-allyl-6-methoxy-1-oxo-1,2,3,4-tetrahydronaphthalen-2-yl)acetate.

Ethyl 2-(2-allyl-6-methoxy-1-oxo-1,2,3,4-tetrahydronaphthalen-2-yl)acetate (CAS 2219339-66-7), molecular formula C18H22O4 and molecular weight 302.36 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Ethyl 2-(2-allyl-6-methoxy-1-oxo-1,2,3,4-tetrahydronaphthalen-2-yl)acetate (C18H22O4) contains a flavonoid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 302.36 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
