Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6,7-Dihydro-5H-pyrrolo[1,2-a]imidazole-3-sulphonyl chloride.
CATO supplies 6,7-Dihydro-5H-pyrrolo[1,2-a]imidazole-3-sulphonyl chloride (CAS 914637-94-8), a certified reference material (molecular formula C6H7ClN2O2S, MW 206.65 g/mol) for analytical method development and quality control.
6,7-Dihydro-5H-pyrrolo[1,2-a]imidazole-3-sulphonyl chloride (C6H7ClN2O2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. It is notably hygroscopic, 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
