4-Hydroxybenzoic acid-ethyl ester sodium CAS 35285-68-8

Description

Compared with other compounds in its class, the molecular weight of 188.16 g/mol gives 4-Hydroxybenzoic acid-ethyl ester sodium distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 4-Hydroxybenzoic acid-ethyl ester sodium (CAS 35285-68-8), a certified reference material (molecular formula C9H9O3Na, MW 188.16 g/mol) for analytical method development and quality control.

4-Hydroxybenzoic acid-ethyl ester sodium (C9H9O3Na) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 4-Hydroxybenzoic acid-ethyl ester sodium 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.
