4-(Thiophen-2-yl)-4,6,7,8-tetrahydro-1H-5,8-ethanopyrido[3,2-d]pyrimidine-2(3H)-thione CAS 82955-23-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(Thiophen-2-yl)-4,6,7,8-tetrahydro-1H-5,8-ethanopyrido[3,2-d]pyrimidine-2(3H)-thione.

4-(Thiophen-2-yl)-4,6,7,8-tetrahydro-1H-5,8-ethanopyrido[3,2-d]pyrimidine-2(3H)-thione (CAS 82955-23-5), molecular formula C13H15N3S2 and molecular weight 277.41 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-(Thiophen-2-yl)-4,6,7,8-tetrahydro-1H-5,8-ethanopyrido[3,2-d]pyrimidine-2(3H)-thione (C13H15N3S2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. 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).

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 4-(Thiophen-2-yl)-4,6,7,8-tetrahydro-1H-5,8-ethanopyrido[3,2-d]pyrimidine-2(3H)-thione 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.
