Chemical Structure

6-Iodothymidine CAS 31458-38-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 252.01 g/mol gives 6-Iodothymidine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 6-Iodothymidine (CAS 31458-38-5), a certified reference material (molecular formula C5H5IN2O2, MW 252.01 g/mol) for analytical method development and quality control.

6-Iodothymidine (C5H5IN2O2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 6-Iodothymidine 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.
