Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (3-Amino-6-(4-chlorophenyl)thieno[2,3-b]pyridin-2-yl)(4-bromophenyl)methanone.
(3-Amino-6-(4-chlorophenyl)thieno[2,3-b]pyridin-2-yl)(4-bromophenyl)methanone (CAS 1177750-52-5), molecular formula C20H12BrClN2OS and molecular weight 443.74 g/mol, is a CATO reference standard with documented purity and traceability.
(3-Amino-6-(4-chlorophenyl)thieno[2,3-b]pyridin-2-yl)(4-bromophenyl)methanone (C20H12BrClN2OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine/bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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-Amino-6-(4-chlorophenyl)thieno[2,3-b]pyridin-2-yl)(4-bromophenyl)methanone 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.
