Chemical Structure
Description
CATO supplies 4-Chloro-1,3,5-trimethyl-1H-pyrazole (CAS 56079-15-3), a certified reference material (molecular formula C6H9ClN2, MW 144.60 g/mol) for analytical method development and quality control.
Structurally, 4-Chloro-1,3,5-trimethyl-1H-pyrazole (C6H9ClN2) contains a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 144.60 g/mol, it falls into the low-molecular-weight range. 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.
