1-methylpiperazine-2,5-dione CAS 5625-52-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-methylpiperazine-2,5-dione.

1-methylpiperazine-2,5-dione (CAS 5625-52-5) is a high-purity analytical reference standard with the molecular formula C5H8N2O2 and a molecular weight of 128.13 g/mol.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 1-methylpiperazine-2,5-dione is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 128.13 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).

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.
