Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 198.65 g/mol gives Ethyl 3-Chlorophenylacetate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ethyl 3-Chlorophenylacetate (CAS 14062-29-4) is a high-purity analytical reference standard with the molecular formula C10H11ClO2 and a molecular weight of 198.65 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, Ethyl 3-Chlorophenylacetate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 198.65 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
