Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3,4-Dimethyl-3-(3-methylphenyl)propiophenone.
3,4-Dimethyl-3-(3-methylphenyl)propiophenone (CAS 898790-81-3) is a high-purity analytical reference standard with the molecular formula C18H20O and a molecular weight of 252.35 g/mol.
3,4-Dimethyl-3-(3-methylphenyl)propiophenone (C18H20O) contains a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
CATO manufactures 3,4-Dimethyl-3-(3-methylphenyl)propiophenone under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
