2,5-Dichlorothiazolo[5,4-d]pyrimidine CAS 13479-89-5

Description

Compared with other compounds in its class, the molecular weight of 206.05 g/mol gives 2,5-Dichlorothiazolo[5,4-d]pyrimidine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2,5-Dichlorothiazolo[5,4-d]pyrimidine (CAS 13479-89-5) is a high-purity analytical reference standard with the molecular formula C5HCl2N3S and a molecular weight of 206.05 g/mol.

The molecular framework of 2,5-Dichlorothiazolo[5,4-d]pyrimidine (C5HCl2N3S) is characterized by a nitrile group, sulfur-containing functionality, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), 2,5-Dichlorothiazolo[5,4-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.
