5,6-Diaminopyrimidine-2,4-dithiol 4,5-Diamino-2,6-dimercaptopyrimidine 5,6-Diamino-2,4(1H,3H)-pyrimidinedithione 31295-41-7 CAS 31295-41-7 chemical structure

Description

The occurrence of 5,6-Diaminopyrimidine-2,4-dithiol 4,5-Diamino-2,6-dimercaptopyrimidine 5,6-Diamino-2,4(1H,3H)-pyrimidinedithione 31295-41-7 is closely related to sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 5,6-Diaminopyrimidine-2,4-dithiol 4,5-Diamino-2,6-dimercaptopyrimidine 5,6-Diamino-2,4(1H,3H)-pyrimidinedithione 31295-41-7 (CAS 31295-41-7), a certified reference material (molecular formula C4H12N4S2, MW 180.29 g/mol) for analytical method development and quality control.

Owing to sulfur-containing functionality, 5,6-Diaminopyrimidine-2,4-dithiol 4,5-Diamino-2,6-dimercaptopyrimidine 5,6-Diamino-2,4(1H,3H)-pyrimidinedithione 31295-41-7 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 180.29 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.

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.
