Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,3-Difluoro-4-methoxybenzoic Acid.
CATO supplies 2,3-Difluoro-4-methoxybenzoic Acid (CAS 329014-60-0), a certified reference material (molecular formula C8H6F2O3, MW 188.13 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 2,3-Difluoro-4-methoxybenzoic Acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 188.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2,3-Difluoro-4-methoxybenzoic 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.
