Chemical Structure

tert-Butyl thiomorpholine-4-carboxylate CAS 220655-09-4 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.

tert-Butyl thiomorpholine-4-carboxylate (CAS 220655-09-4), molecular formula C9H17NO2S and molecular weight 203.30 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of tert-Butyl thiomorpholine-4-carboxylate (C9H17NO2S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. 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), tert-Butyl thiomorpholine-4-carboxylate 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.
