7-Chloro-5-propyl-2,3-dihydrobenzo[b][1,4]thiazepin-4(5H)-one CAS 303987-56-6

Description

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.

7-Chloro-5-propyl-2,3-dihydrobenzo[b][1,4]thiazepin-4(5H)-one (CAS 303987-56-6) is a high-purity analytical reference standard with the molecular formula C12H14ClNOS and a molecular weight of 255.76 g/mol.

The molecular framework of 7-Chloro-5-propyl-2,3-dihydrobenzo[b][1,4]thiazepin-4(5H)-one (C12H14ClNOS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), 7-Chloro-5-propyl-2,3-dihydrobenzo[b][1,4]thiazepin-4(5H)-one 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.
