Description

Compared with other compounds in its class, the molecular weight of 321.87 g/mol gives 4-Chloro-5,6,7,8-tetrahydro-2-(1-piperidinylmethyl)[1]benzothieno[2,3-d]pyrimidine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-Chloro-5,6,7,8-tetrahydro-2-(1-piperidinylmethyl)[1]benzothieno[2,3-d]pyrimidine (CAS 731827-03-5), molecular formula C16H20ClN3S and molecular weight 321.87 g/mol, is a CATO reference standard with documented purity and traceability.

4-Chloro-5,6,7,8-tetrahydro-2-(1-piperidinylmethyl)[1]benzothieno[2,3-d]pyrimidine (C16H20ClN3S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. Halogen substitution raises its density and boiling point, 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
