Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 167.17 g/mol gives 3-Methyl-5h,6h,7h-pyrrolo[2,1-c][1,2,4]triazole-5-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Methyl-5h,6h,7h-pyrrolo[2,1-c][1,2,4]triazole-5-carboxylic acid (CAS 160205-15-2), molecular formula C7H9N3O2 and molecular weight 167.17 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 3-Methyl-5h,6h,7h-pyrrolo[2,1-c][1,2,4]triazole-5-carboxylic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 167.17 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
