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 (S)-5-Methyl-1,3-dioxolane-2,4-dione.
CATO supplies (S)-5-Methyl-1,3-dioxolane-2,4-dione (CAS 5997-42-2), a certified reference material (molecular formula C4H4O4, MW 116.07 g/mol) for analytical method development and quality control.
The molecular framework of (S)-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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
