Chemical Structure

4-Ethylcatechol-d CAS 1189508-64-2 chemical structure

Description

CATO supplies 4-Ethylcatechol-d (CAS 1189508-64-2), a certified reference material (molecular formula C8H5D5O2, MW 143.19 g/mol) for analytical method development and quality control.

Based on its molecular formula C8H5D5O2, 4-Ethylcatechol-d contains deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 143.19 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 4-Ethylcatechol-d 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.
