Chemical Structure

Ethyl 2-chloro-5-methylbenzoate CAS 945262-03-3 chemical structure

Description

The occurrence of Ethyl 2-chloro-5-methylbenzoate 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.

Ethyl 2-chloro-5-methylbenzoate (CAS 945262-03-3), molecular formula C10H11ClO2 and molecular weight 198.65 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C10H11ClO2, Ethyl 2-chloro-5-methylbenzoate contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 198.65 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), Ethyl 2-chloro-5-methylbenzoate 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.
