Description
As a certified reference material (CRM), 2,6-Dimethoxybenzoic 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.
2,6-Dimethoxybenzoic Acid (CAS 1466-76-8) is a high-purity analytical reference standard with the molecular formula C9H10O4 and a molecular weight of 182.17 g/mol.
The molecular framework of 2,6-Dimethoxybenzoic Acid (C9H10O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
