Chemical Structure

Celecoxib Impurity 27 CAS 556-53-6 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

Celecoxib Impurity 27 (CAS 556-53-6) is a high-purity analytical reference standard with the molecular formula C3H9NHCl and a molecular weight of 95.57 g/mol.

The molecular framework of Celecoxib Impurity 27 (C3H9NHCl) is characterized by 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
