Chemical Structure

5-Chlorothiazolo[5,4-d]pyrimidin-2-amine CAS 1006879-06-6 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 186.62 g/mol gives 5-Chlorothiazolo[5,4-d]pyrimidin-2-amine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 5-Chlorothiazolo[5,4-d]pyrimidin-2-amine (CAS 1006879-06-6), a certified reference material (molecular formula C5H3ClN4S, MW 186.62 g/mol) for analytical method development and quality control.

Based on its molecular formula C5H3ClN4S, 5-Chlorothiazolo[5,4-d]pyrimidin-2-amine contains a nitrile group, sulfur-containing functionality, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 186.62 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
