Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6-bromo-2,4-dichloro-thieno[3,2-d]pyrimidine.
6-bromo-2,4-dichloro-thieno[3,2-d]pyrimidine (CAS 1311275-35-0) is a high-purity analytical reference standard with the molecular formula C6H9BrCl2N2S and a molecular weight of 292.02 g/mol.
Owing to a nitrile group, sulfur-containing functionality, chlorine/bromine substitution, 6-bromo-2,4-dichloro-thieno[3,2-d]pyrimidine is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 292.02 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
