2-(2,6-Difluoro-3-methoxyphenyl)acetic acid CAS 886498-65-3 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-(2,6-Difluoro-3-methoxyphenyl)acetic acid.

2-(2,6-Difluoro-3-methoxyphenyl)acetic acid (CAS 886498-65-3) is a high-purity analytical reference standard with the molecular formula C9H8F2O3 and a molecular weight of 202.15 g/mol.

2-(2,6-Difluoro-3-methoxyphenyl)acetic acid (C9H8F2O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine 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).

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-(2,6-Difluoro-3-methoxyphenyl)acetic 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.
