Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6-Methoxybenzo[d][1,3]dioxole-4-carboxylic acid.
6-Methoxybenzo[d][1,3]dioxole-4-carboxylic acid (CAS 401811-79-8), molecular formula C9H8O5 and molecular weight 196.16 g/mol, is a CATO reference standard with documented purity and traceability.
6-Methoxybenzo[d][1,3]dioxole-4-carboxylic acid (C9H8O5) 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.
As a certified reference material (CRM), 6-Methoxybenzo[d][1,3]dioxole-4-carboxylic 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.
