Chemical Structure
Description
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.
CATO supplies Methyl 2-hydroxy-2-(4-hydroxyphenyl)acetate (CAS 68758-69-0), a certified reference material (molecular formula C9H10O4, MW 182.17 g/mol) for analytical method development and quality control.
Methyl 2-hydroxy-2-(4-hydroxyphenyl)acetate (C9H10O4) 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).
As a certified reference material (CRM), Methyl 2-hydroxy-2-(4-hydroxyphenyl)acetate 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.
