N-(5-bromothieno[2,3-d]pyrimidin-4-yl)-4-chlorobenzenesulfonamide CAS 2007921-12-0

Description

As a certified reference material (CRM), N-(5-bromothieno[2,3-d]pyrimidin-4-yl)-4-chlorobenzenesulfonamide 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.

CATO supplies N-(5-bromothieno[2,3-d]pyrimidin-4-yl)-4-chlorobenzenesulfonamide (CAS 2007921-12-0), a certified reference material (molecular formula C12H7BrClN3O2S2, MW 404.69 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, N-(5-bromothieno[2,3-d]pyrimidin-4-yl)-4-chlorobenzenesulfonamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 404.69 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.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
