Chemical Structure

5-Methyl-4-piperazinothieno[2,3-d]pyrimidine CAS 782475-77-8 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Methyl-4-piperazinothieno[2,3-d]pyrimidine.

5-Methyl-4-piperazinothieno[2,3-d]pyrimidine (CAS 782475-77-8) is a high-purity analytical reference standard with the molecular formula C11H14N4S and a molecular weight of 234.32 g/mol.

5-Methyl-4-piperazinothieno[2,3-d]pyrimidine (C11H14N4S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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.

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.
