3,6-Dimethylchromone CAS 57646-01-2 chemical structure

Description

As a certified reference material (CRM), 3,6-Dimethylchromone 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.

3,6-Dimethylchromone (CAS 57646-01-2) is a high-purity analytical reference standard with the molecular formula C11H10O2 and a molecular weight of 174.20 g/mol.

Based on its molecular formula C11H10O2, 3,6-Dimethylchromone contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 174.20 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
