7-Nitrobenzo[d]isothiazol-3-amine CAS 90407-29-7

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7-Nitrobenzo[d]isothiazol-3-amine.

CATO supplies 7-Nitrobenzo[d]isothiazol-3-amine (CAS 90407-29-7), a certified reference material (molecular formula C7H5N3O2S, MW 195.20 g/mol) for analytical method development and quality control.

Structurally, 7-Nitrobenzo[d]isothiazol-3-amine (C7H5N3O2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 195.20 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures 7-Nitrobenzo[d]isothiazol-3-amine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
