Ethyl 4-hydroxy-3,5-dimethoxybenzoate CAS 3943-80-4

Description

The occurrence of Ethyl 4-hydroxy-3,5-dimethoxybenzoate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Ethyl 4-hydroxy-3,5-dimethoxybenzoate (CAS 3943-80-4) is a high-purity analytical reference standard with the molecular formula C11H14O5 and a molecular weight of 226.23 g/mol.

Structurally, Ethyl 4-hydroxy-3,5-dimethoxybenzoate (C11H14O5) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 226.23 g/mol, it falls into the medium-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.

As a certified reference material (CRM), Ethyl 4-hydroxy-3,5-dimethoxybenzoate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
