Chemical Structure

Methsuximide-D5 CAS 1189980-63-9 chemical structure

Description

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.

Methsuximide-D5 (CAS 1189980-63-9) is a high-purity analytical reference standard with the molecular formula C12H8D5NO2 and a molecular weight of 208.27 g/mol.

Structurally, Methsuximide-D5 (C12H8D5NO2) contains deuterium isotope labeling, an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.5, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 208.27 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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