Chemical Structure

1-Cyclooctylthiourea CAS 128169-48-2 chemical structure

Description

CATO supplies 1-Cyclooctylthiourea (CAS 128169-48-2), a certified reference material (molecular formula C9H18N2S, MW 186.32 g/mol) for analytical method development and quality control.

Owing to a nitrile group, sulfur-containing functionality, 1-Cyclooctylthiourea is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 186.32 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

As a certified reference material (CRM), 1-Cyclooctylthiourea 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.
