Chemical Structure

3-Methyl-1,2-cyclopentanedione CAS 765-70-8 chemical structure

Description

As a certified reference material (CRM), 3-Methyl-1,2-cyclopentanedione 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.

3-Methyl-1,2-cyclopentanedione (CAS 765-70-8) is a high-purity analytical reference standard with the molecular formula C6H8O2 and a molecular weight of 112.13 g/mol.

The molecular framework of 3-Methyl-1,2-cyclopentanedione (C6H8O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
