Description

Compared with other compounds in its class, the molecular weight of 206.69 g/mol gives 4-chlorothieno[3,2-d]pyrimidine-6-carbaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-chlorothieno[3,2-d]pyrimidine-6-carbaldehyde (CAS 875340-14-0) is a high-purity analytical reference standard with the molecular formula C7H11ClN2OS and a molecular weight of 206.69 g/mol.

Structurally, 4-chlorothieno[3,2-d]pyrimidine-6-carbaldehyde (C7H11ClN2OS) contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 206.69 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.
