6-Cyclopropylbenzo[d]isothiazole-3-carboxylic acid CAS 858671-75-7

Description

Compared with other compounds in its class, the molecular weight of 219.26 g/mol gives 6-Cyclopropylbenzo[d]isothiazole-3-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

6-Cyclopropylbenzo[d]isothiazole-3-carboxylic acid (CAS 858671-75-7), molecular formula C11H9NO2S and molecular weight 219.26 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 6-Cyclopropylbenzo[d]isothiazole-3-carboxylic acid (C11H9NO2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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

As a certified reference material (CRM), 6-Cyclopropylbenzo[d]isothiazole-3-carboxylic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
