Chemical Structure
Description
As a certified reference material (CRM), Dimethyl 1-isopropylcyclopentane-1,3-dicarboxylate 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.
Dimethyl 1-isopropylcyclopentane-1,3-dicarboxylate (CAS 1959577-13-9), 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, Dimethyl 1-isopropylcyclopentane-1,3-dicarboxylate 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.
