4-(((5,6-Dimethylthieno[2,3-d]pyrimidin-4-yl)thio)methyl)-3,5-dimethylisoxazole CAS 315692-61-6

Description

4-(((5,6-Dimethylthieno[2,3-d]pyrimidin-4-yl)thio)methyl)-3,5-dimethylisoxazole (CAS 315692-61-6) is a high-purity analytical reference standard with the molecular formula C14H15N3OS2 and a molecular weight of 305.42 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 4-(((5,6-Dimethylthieno[2,3-d]pyrimidin-4-yl)thio)methyl)-3,5-dimethylisoxazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 305.42 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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-(((5,6-Dimethylthieno[2,3-d]pyrimidin-4-yl)thio)methyl)-3,5-dimethylisoxazole 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.
