Chemical Structure

Ethyl 3-bromo-4-(3,4-dichlorophenyl)-4-oxobutanoate CAS 35158-45-3 chemical structure

Description

The occurrence of Ethyl 3-bromo-4-(3,4-dichlorophenyl)-4-oxobutanoate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Ethyl 3-bromo-4-(3,4-dichlorophenyl)-4-oxobutanoate (CAS 35158-45-3), a certified reference material (molecular formula C12H11BrCl2O3, MW 354.02 g/mol) for analytical method development and quality control.

Structurally, Ethyl 3-bromo-4-(3,4-dichlorophenyl)-4-oxobutanoate (C12H11BrCl2O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 354.02 g/mol, it falls into the moderately-high-molecular-weight range. 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.

As a certified reference material (CRM), Ethyl 3-bromo-4-(3,4-dichlorophenyl)-4-oxobutanoate 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.
