Methyl 2-((5-methyl-4-nitro-1H-pyrazol-3-yl)thio)acetate CAS 1240284-08-5

Description

The occurrence of Methyl 2-((5-methyl-4-nitro-1H-pyrazol-3-yl)thio)acetate is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Methyl 2-((5-methyl-4-nitro-1H-pyrazol-3-yl)thio)acetate (CAS 1240284-08-5), molecular formula C7H9N3O4S and molecular weight 231.23 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, Methyl 2-((5-methyl-4-nitro-1H-pyrazol-3-yl)thio)acetate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 231.23 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.
