Chemical Structure
Description
As a certified reference material (CRM), 2-Ethyl 5-methyl 7-hydroxybenzo[d][1,3]dioxole-2,5-dicarboxylate 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.
CATO supplies 2-Ethyl 5-methyl 7-hydroxybenzo[d][1,3]dioxole-2,5-dicarboxylate (CAS 1956328-23-6), a certified reference material (molecular formula C12H12O7, MW 268.22 g/mol) for analytical method development and quality control.
2-Ethyl 5-methyl 7-hydroxybenzo[d][1,3]dioxole-2,5-dicarboxylate (C12H12O7) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
