Chemical Structure
Description
5-(Chloromethyl)-3-nitro-1-((2-(trimethylsilyl)ethoxy)methyl)-1H-pyrazole (CAS 2738982-26-6) is a high-purity analytical reference standard with the molecular formula C10H18ClN3O3Si and a molecular weight of 291.81 g/mol.
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 5-(Chloromethyl)-3-nitro-1-((2-(trimethylsilyl)ethoxy)methyl)-1H-pyrazole is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 291.81 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 5-(Chloromethyl)-3-nitro-1-((2-(trimethylsilyl)ethoxy)methyl)-1H-pyrazole 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.
