Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (R)-5-Methyl-1,3-dioxolane-2,4-dione.
(R)-5-Methyl-1,3-dioxolane-2,4-dione (CAS 91049-50-2) is a high-purity analytical reference standard with the molecular formula C4H4O4 and a molecular weight of 116.07 g/mol.
The molecular framework of (R)-5-Methyl-1,3-dioxolane-2,4-dione (C4H4O4) is characterized by a carbohydrate-derived structure. 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.
