5-bromothieno[2,3-d]pyrimidin-4-amine CAS 1337532-92-9

Description

Compared with other compounds in its class, the molecular weight of 238.15 g/mol gives 5-bromothieno[2,3-d]pyrimidin-4-amine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-bromothieno[2,3-d]pyrimidin-4-amine (CAS 1337532-92-9) is a high-purity analytical reference standard with the molecular formula C6H12BrN3S and a molecular weight of 238.15 g/mol.

Owing to a nitrile group, sulfur-containing functionality, bromine substitution, 5-bromothieno[2,3-d]pyrimidin-4-amine is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 238.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

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.
