4-Chloro-6-methyl-2-phenylthieno[2,3-d]pyrimidine CAS 1351385-18-6

Description

Compared with other compounds in its class, the molecular weight of 260.74 g/mol gives 4-Chloro-6-methyl-2-phenylthieno[2,3-d]pyrimidine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-Chloro-6-methyl-2-phenylthieno[2,3-d]pyrimidine (CAS 1351385-18-6) is a high-purity analytical reference standard with the molecular formula C13H9ClN2S and a molecular weight of 260.74 g/mol.

The molecular framework of 4-Chloro-6-methyl-2-phenylthieno[2,3-d]pyrimidine (C13H9ClN2S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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

As a certified reference material (CRM), 4-Chloro-6-methyl-2-phenylthieno[2,3-d]pyrimidine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
