4-amino-5,6-dimethyl thieno(2,3-d)pyrimidin-2(1H)-one hydrochloride CAS 1033366-59-4 chemical structure

Description

The occurrence of 4-amino-5,6-dimethyl thieno(2,3-d)pyrimidin-2(1H)-one hydrochloride is closely related to a structurally diverse molecular composition in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-amino-5,6-dimethyl thieno(2,3-d)pyrimidin-2(1H)-one hydrochloride (CAS 1033366-59-4), molecular formula N/A and molecular weight N/A g/mol, is a CATO reference standard with documented purity and traceability.

4-amino-5,6-dimethyl thieno(2,3-d)pyrimidin-2(1H)-one hydrochloride is supplied as a fully characterized reference material; its structural identity, assigned purity, and stability data are documented in the batch-specific Certificate of Analysis (COA).

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.
