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 Methyl (3-chloro-1-methyl-1H-pyrazol-5-yl)carbamate.
Methyl (3-chloro-1-methyl-1H-pyrazol-5-yl)carbamate (CAS 695184-12-4) is a high-purity analytical reference standard with the molecular formula C6H8ClN3O2 and a molecular weight of 189.60 g/mol.
The molecular framework of Methyl (3-chloro-1-methyl-1H-pyrazol-5-yl)carbamate (C6H8ClN3O2) is characterized by an amide group, a carboxylic acid 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
