Chemical Structure
Description
2-Chloro-N-(prop-2-yn-1-yl)-N-(1,3,5-trimethyl-1H-pyrazol-4-yl)acetamide (CAS 87675-22-7), molecular formula C11H14ClN3O and molecular weight 239.70 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 2-Chloro-N-(prop-2-yn-1-yl)-N-(1,3,5-trimethyl-1H-pyrazol-4-yl)acetamide is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 239.70 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 2-Chloro-N-(prop-2-yn-1-yl)-N-(1,3,5-trimethyl-1H-pyrazol-4-yl)acetamide 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.
