Chemical Structure
Description
The occurrence of 2-(2,4-Dichlorophenoxy)-2-methylpropanoic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-(2,4-Dichlorophenoxy)-2-methylpropanoic acid (CAS 1914-66-5) is a high-purity analytical reference standard with the molecular formula C10H10Cl2O3 and a molecular weight of 249.09 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 2-(2,4-Dichlorophenoxy)-2-methylpropanoic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 249.09 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), 2-(2,4-Dichlorophenoxy)-2-methylpropanoic 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.
