Chemical Structure

Ethyl Maltol-d5 CAS CATO-CCFD201836 chemical structure

Description

As a certified reference material (CRM), Ethyl Maltol-d5 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.

Ethyl Maltol-d5 (CAS CATO-CCFD201836), molecular formula C7H3D5O3 and molecular weight 145.17 g/mol, is a CATO reference standard with documented purity and traceability.

Ethyl Maltol-d5 (C7H3D5O3) contains deuterium isotope labeling, 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.
