Ethyl 3-Amino-3-(3,5-dimethoxyphenyl)propanoate Oxalate CAS 1177323-83-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 3-Amino-3-(3,5-dimethoxyphenyl)propanoate Oxalate.

Ethyl 3-Amino-3-(3,5-dimethoxyphenyl)propanoate Oxalate (CAS 1177323-83-9), molecular formula C13H19NO4C2H2O4 and molecular weight 343.33 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Ethyl 3-Amino-3-(3,5-dimethoxyphenyl)propanoate Oxalate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 343.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
