Chemical Structure

Tirofiban Impurity 111 CAS 100-43-6 chemical structure

Description

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

CATO supplies Tirofiban Impurity 111 (CAS 100-43-6), a pharmacopoeial impurity reference standard (molecular formula C7H7N, MW 105.14 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a nitrile group, an aromatic ring system, Tirofiban Impurity 111 is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 105.14 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.

As a certified reference material (CRM), Tirofiban Impurity 111 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.
