6,7,8,9-Tetrahydrothieno[3',2':4,5]pyrimido[1,2-a]azepin-11(5H)-one CAS 120079-43-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6,7,8,9-Tetrahydrothieno[3',2':4,5]pyrimido[1,2-a]azepin-11(5H)-one.

6,7,8,9-Tetrahydrothieno[3',2':4,5]pyrimido[1,2-a]azepin-11(5H)-one (CAS 120079-43-8) is a high-purity analytical reference standard with the molecular formula C11H12N2OS and a molecular weight of 220.29 g/mol.

The molecular framework of 6,7,8,9-Tetrahydrothieno[3',2':4,5]pyrimido[1,2-a]azepin-11(5H)-one (C11H12N2OS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, 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.

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 6,7,8,9-Tetrahydrothieno[3',2':4,5]pyrimido[1,2-a]azepin-11(5H)-one 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.
