Compared with other compounds in its class, the molecular weight of 128.58 g/mol gives Tirofiban Impurity N16 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Tirofiban Impurity N16 (CAS 594-44-5) is a certified pharmaceutical impurity reference standard with the molecular formula C2H5ClO2S and a molecular weight of 128.58 g/mol.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, Tirofiban Impurity N16 is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 128.58 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 manufactures Tirofiban Impurity N16 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
