Chemical Structure

1-Thia-4-azaspiro[4.4]nonane CAS 176-30-7 chemical structure

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.

CATO supplies 1-Thia-4-azaspiro[4.4]nonane (CAS 176-30-7), a certified reference material (molecular formula C7H13NS, MW 143.25 g/mol) for analytical method development and quality control.

The molecular framework of 1-Thia-4-azaspiro[4.4]nonane (C7H13NS) is characterized by a nitrile group, sulfur-containing functionality. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

As a certified reference material (CRM), 1-Thia-4-azaspiro[4.4]nonane 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.
