Chemical Structure

1-Methyl-3-(trifluoromethoxy)-1H-pyrazole-5-carboxylic acid CAS 2407482-79-3 chemical structure

Description

The occurrence of 1-Methyl-3-(trifluoromethoxy)-1H-pyrazole-5-carboxylic acid is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-Methyl-3-(trifluoromethoxy)-1H-pyrazole-5-carboxylic acid (CAS 2407482-79-3) is a high-purity analytical reference standard with the molecular formula C6H5F3N2O3 and a molecular weight of 210.11 g/mol.

Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 1-Methyl-3-(trifluoromethoxy)-1H-pyrazole-5-carboxylic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 210.11 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
