Chemical Structure
Description
As a certified reference material (CRM), Diethyl 2,2'-(cyclobutane-1,1-diyl)diacetate 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.
Diethyl 2,2'-(cyclobutane-1,1-diyl)diacetate (CAS 51008-00-5), molecular formula C12H20O4 and molecular weight 228.28 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Diethyl 2,2'-(cyclobutane-1,1-diyl)diacetate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 228.28 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
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.
