Chemical Structure

2-(Chloromethyl)-5-phenylthieno[2,3-d]pyrimidin-4-ol CAS 89567-07-7 chemical structure

Description

The occurrence of 2-(Chloromethyl)-5-phenylthieno[2,3-d]pyrimidin-4-ol is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-(Chloromethyl)-5-phenylthieno[2,3-d]pyrimidin-4-ol (CAS 89567-07-7) is a high-purity analytical reference standard with the molecular formula C13H9ClN2OS and a molecular weight of 276.74 g/mol.

Structurally, 2-(Chloromethyl)-5-phenylthieno[2,3-d]pyrimidin-4-ol (C13H9ClN2OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 276.74 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).

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.
