Description
As a certified reference material (CRM), Dibutyl 2-ethylmalonate 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.
Dibutyl 2-ethylmalonate (CAS 1113-92-4), molecular formula C25H22PCl and molecular weight 388.88 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Dibutyl 2-ethylmalonate (C25H22PCl) contains organophosphorus functionality, chlorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 14.5, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 388.88 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
