Chemical Structure

Ethyl 4,4-dichlorocyclohexanecarboxylate CAS 444578-35-2 chemical structure

Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

Ethyl 4,4-dichlorocyclohexanecarboxylate (CAS 444578-35-2), molecular formula C9H14Cl2O2 and molecular weight 225.11 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, Ethyl 4,4-dichlorocyclohexanecarboxylate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 225.11 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.

As a certified reference material (CRM), Ethyl 4,4-dichlorocyclohexanecarboxylate 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.
