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 2-(7-Chlorobenzo[d][1,3]dioxol-5-yl)-2-hydroxyacetic acid (CAS 1248448-40-9), a certified reference material (molecular formula C9H7ClO5, MW 230.60 g/mol) for analytical method development and quality control.

2-(7-Chlorobenzo[d][1,3]dioxol-5-yl)-2-hydroxyacetic acid (C9H7ClO5) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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), 2-(7-Chlorobenzo[d][1,3]dioxol-5-yl)-2-hydroxyacetic acid 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.
