Chemical Structure
Description
The occurrence of (1h-Pyrazol-3-yl)methanol hydrochloride is closely related to an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(1h-Pyrazol-3-yl)methanol hydrochloride (CAS 270920-41-7) is a high-purity analytical reference standard with the molecular formula C4H6N2OHCl and a molecular weight of 134.56 g/mol.
(1h-Pyrazol-3-yl)methanol hydrochloride (C4H6N2OHCl) 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.
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.
