Chemical Structure

Dl-alpha-methylproline hbr CAS 1346136-61-5 chemical structure

Description

Dl-alpha-methylproline hbr (CAS 1346136-61-5), molecular formula C6H11NO2HBr and molecular weight 210.07 g/mol, is a CATO reference standard with documented purity and traceability.

Dl-alpha-methylproline hbr (C6H11NO2HBr) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

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.
