Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

SO5F79G1MJ 68555-63-5 2-Methyl-3-(1-oxopropoxy)-4H-pyran-4-one 4H-Pyran-4-one, 2-methyl-3-(1-oxopropoxy)- EINECS 271-440-0 Maltol propionate UNII-SO5F79G1MJ (CAS 68555-63-5) is a high-purity analytical reference standard with the molecular formula C9H10O4 and a molecular weight of 182.17 g/mol.

Structurally, SO5F79G1MJ 68555-63-5 2-Methyl-3-(1-oxopropoxy)-4H-pyran-4-one 4H-Pyran-4-one, 2-methyl-3-(1-oxopropoxy)- EINECS 271-440-0 Maltol propionate UNII-SO5F79G1MJ (C9H10O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 182.17 g/mol, it falls into the medium-molecular-weight range. 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).

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.
