Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 362.01 g/mol gives Ethyl 6,8-dibromo-2H-chromene-3-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Ethyl 6,8-dibromo-2H-chromene-3-carboxylate (CAS 885271-30-7), a certified reference material (molecular formula C12H10Br2O3, MW 362.01 g/mol) for analytical method development and quality control.
Structurally, Ethyl 6,8-dibromo-2H-chromene-3-carboxylate (C12H10Br2O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 362.01 g/mol, it falls into the moderately-high-molecular-weight range. 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 6,8-dibromo-2H-chromene-3-carboxylate 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.
