Chemical Structure

tert-butyl 3-(chloromethyl)-1H-pyrazole-1-carboxylate CAS 1823940-84-6 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 220.70 g/mol gives tert-butyl 3-(chloromethyl)-1H-pyrazole-1-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

tert-butyl 3-(chloromethyl)-1H-pyrazole-1-carboxylate (CAS 1823940-84-6), molecular formula C9H17ClN2O2 and molecular weight 220.70 g/mol, is a CATO reference standard with documented purity and traceability.

tert-butyl 3-(chloromethyl)-1H-pyrazole-1-carboxylate (C9H17ClN2O2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. 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.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures tert-butyl 3-(chloromethyl)-1H-pyrazole-1-carboxylate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
