Chemical Structure

Thiazolo[4,5-d]pyrimidine-2,7-diamine hydrate CAS 857970-33-3 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.

Thiazolo[4,5-d]pyrimidine-2,7-diamine hydrate (CAS 857970-33-3) is a high-purity analytical reference standard with the molecular formula C5H5N5SH2O and a molecular weight of 185.20 g/mol.

Structurally, Thiazolo[4,5-d]pyrimidine-2,7-diamine hydrate (C5H5N5SH2O) contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 185.20 g/mol, it falls into the medium-molecular-weight range. 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).

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.
