The occurrence of rac Pseudoephedrine Hydrochloride is closely related to an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
rac Pseudoephedrine Hydrochloride (CAS 56979-55-6) is a high-purity analytical reference standard with the molecular formula C10H15NOHCl and a molecular weight of 201.69 g/mol.
Based on its molecular formula C10H15NOHCl, rac Pseudoephedrine Hydrochloride contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 201.69 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
As a certified reference material (CRM), rac Pseudoephedrine Hydrochloride 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.
