Chemical Structure
Description
As a certified reference material (CRM), Diethyl 2,6-dibromoheptanedioate 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.
CATO supplies Diethyl 2,6-dibromoheptanedioate (CAS 868-68-8), a certified reference material (molecular formula C11H18Br2O4, MW 374.07 g/mol) for analytical method development and quality control.
Structurally, Diethyl 2,6-dibromoheptanedioate (C11H18Br2O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 374.07 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.
