4-chloro-6-nitrothieno[2,3-d]pyrimidine CAS 56844-13-4

Description

The occurrence of 4-chloro-6-nitrothieno[2,3-d]pyrimidine is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-chloro-6-nitrothieno[2,3-d]pyrimidine (CAS 56844-13-4), molecular formula C6H2ClN3O2S and molecular weight 215.62 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 4-chloro-6-nitrothieno[2,3-d]pyrimidine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 215.62 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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