Chemical Structure
Description
1-MEthyl-3-pyrrolidin-3-yl-1h-pyrazol-5-ol dihydrochloride (C8H13N3OHCl) contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; 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.
CATO supplies 1-MEthyl-3-pyrrolidin-3-yl-1h-pyrazol-5-ol dihydrochloride (CAS 1532288-31-5), a certified reference material (molecular formula C8H13N3OHCl, MW 203.67 g/mol) for analytical method development and quality control.
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.
