Chemical Structure

Thiomorpholine-3-carboxylic acid 1-oxide hydrochloride CAS 1803566-72-4 chemical structure

Description

The occurrence of Thiomorpholine-3-carboxylic acid 1-oxide hydrochloride is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Thiomorpholine-3-carboxylic acid 1-oxide hydrochloride (CAS 1803566-72-4), molecular formula C5H9NO3SHCl and molecular weight 199.65 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Thiomorpholine-3-carboxylic acid 1-oxide hydrochloride (C5H9NO3SHCl) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. 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.

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), Thiomorpholine-3-carboxylic acid 1-oxide hydrochloride 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.
