Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 192.17 g/mol gives 1'-Methyl-1'h-[1,3'-bipyrazole]-3-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1'-Methyl-1'h-[1,3'-bipyrazole]-3-carboxylic acid (CAS 1507553-53-8), molecular formula C8H8N4O2 and molecular weight 192.17 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, 1'-Methyl-1'h-[1,3'-bipyrazole]-3-carboxylic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 192.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
