Description
CATO manufactures 3-Methyl-3-phenyloxolane-2,5-dione 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.
3-Methyl-3-phenyloxolane-2,5-dione (CAS 14702-34-2) is a high-purity analytical reference standard with the molecular formula C11H10O3 and a molecular weight of 190.20 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 3-Methyl-3-phenyloxolane-2,5-dione is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 190.20 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.
