Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 180.20 g/mol gives 1,4,5,6,7,8-Hexahydrocyclohepta[c]pyrazole-3-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1,4,5,6,7,8-Hexahydrocyclohepta[c]pyrazole-3-carboxylic acid (CAS 856256-63-8), a certified reference material (molecular formula C9H12N2O2, MW 180.20 g/mol) for analytical method development and quality control.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 1,4,5,6,7,8-Hexahydrocyclohepta[c]pyrazole-3-carboxylic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 180.20 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.
