Chemical Structure
Description
3-{4-oxo-3H,4H-thieno[2,3-d]pyrimidin-3-yl}propanoic acid hydrochloride (CAS 1209189-00-3) is a high-purity analytical reference standard with the molecular formula C9H14N2O3SHCl and a molecular weight of 266.74 g/mol.
The molecular framework of 3-{4-oxo-3H,4H-thieno[2,3-d]pyrimidin-3-yl}propanoic acid hydrochloride (C9H14N2O3SHCl) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 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. 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.
As a certified reference material (CRM), 3-{4-oxo-3H,4H-thieno[2,3-d]pyrimidin-3-yl}propanoic acid hydrochloride 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.
