5-(2-Methylphenyl)cyclohexane-1,3-dione CAS 239132-47-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-(2-Methylphenyl)cyclohexane-1,3-dione.

5-(2-Methylphenyl)cyclohexane-1,3-dione (CAS 239132-47-9) is a high-purity analytical reference standard with the molecular formula C13H14O2 and a molecular weight of 202.25 g/mol.

5-(2-Methylphenyl)cyclohexane-1,3-dione (C13H14O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

As a certified reference material (CRM), 5-(2-Methylphenyl)cyclohexane-1,3-dione 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.
