Description
As a certified reference material (CRM), Ethyl 2,5-dichloro-3-methylphenylacetate 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.
Ethyl 2,5-dichloro-3-methylphenylacetate (CAS 1804896-90-9), molecular formula C11H12Cl2O2 and molecular weight 247.12 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, Ethyl 2,5-dichloro-3-methylphenylacetate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 247.12 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.
