Chemical Structure

6-Chloro-7-(piperazine-1-sulfonyl)-3,4-dihydro-2h-1,4-benzoxazin-3-one hydrochloride CAS 1172549-33-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 368.23 g/mol gives 6-Chloro-7-(piperazine-1-sulfonyl)-3,4-dihydro-2h-1,4-benzoxazin-3-one hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

6-Chloro-7-(piperazine-1-sulfonyl)-3,4-dihydro-2h-1,4-benzoxazin-3-one hydrochloride (CAS 1172549-33-5) is a high-purity analytical reference standard with the molecular formula C12H14ClN3O4SHCl and a molecular weight of 368.23 g/mol.

The molecular framework of 6-Chloro-7-(piperazine-1-sulfonyl)-3,4-dihydro-2h-1,4-benzoxazin-3-one hydrochloride (C12H14ClN3O4SHCl) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing 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.
