Azetidine-2-carboxylic acid hydrochloride CAS 69539-48-6

Description

Compared with other compounds in its class, the molecular weight of 137.56 g/mol gives Azetidine-2-carboxylic acid hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Azetidine-2-carboxylic acid hydrochloride (CAS 69539-48-6), molecular formula C4H7NO2HCl and molecular weight 137.56 g/mol, is a CATO reference standard with documented purity and traceability.

Azetidine-2-carboxylic acid hydrochloride (C4H7NO2HCl) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, 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.

As a certified reference material (CRM), Azetidine-2-carboxylic acid 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.
