Chemical Structure

Propamidine CAS 104-32-5 chemical structure

Description

As a certified reference material (CRM), Propamidine 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.

Propamidine (CAS 104-32-5) is a high-purity analytical reference standard with the molecular formula C17H20N4O2 and a molecular weight of 312.37 g/mol.

Propamidine (C17H20N4O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
