Compared with other compounds in its class, the molecular weight of 172.61 g/mol gives 1H-Pyrrolizin-7a(5H)-ol, 2-chloro-2,3-dihydro-5-imino-, (2S,7aS)- distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1H-Pyrrolizin-7a(5H)-ol, 2-chloro-2,3-dihydro-5-imino-, (2S,7aS)- (CAS 71774-49-7), molecular formula C7H9ClN2O and molecular weight 172.61 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1H-Pyrrolizin-7a(5H)-ol, 2-chloro-2,3-dihydro-5-imino-, (2S,7aS)- (C7H9ClN2O) is characterized by an amide group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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 analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
