2-(4-Nitro-1-(2,2,2-trifluoroethyl)-1H-pyrazol-3-yl)acetic acid CAS 1328640-56-7 chemical structure

Description

CATO manufactures 2-(4-Nitro-1-(2,2,2-trifluoroethyl)-1H-pyrazol-3-yl)acetic acid 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.

CATO supplies 2-(4-Nitro-1-(2,2,2-trifluoroethyl)-1H-pyrazol-3-yl)acetic acid (CAS 1328640-56-7), a certified reference material (molecular formula C7H6F3N3O4, MW 253.14 g/mol) for analytical method development and quality control.

Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 2-(4-Nitro-1-(2,2,2-trifluoroethyl)-1H-pyrazol-3-yl)acetic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 253.14 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.
