Chemical Structure
Description
CATO supplies Salbutamol EP Impurity M(Formic Acid) (CAS CATO-C4X-117631), a pharmacopoeial impurity reference standard (molecular formula C14H23NO3CH2O2, MW 299.37 g/mol) used for the identification and quantification of trace impurities in APIs.
The molecular framework of Salbutamol EP Impurity M(Formic Acid) (C14H23NO3CH2O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
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.
