Chemical Structure
Description
3-Chloro-4-(trifluoromethyl)-5,6,7,8-tetrahydropyrido[3,2-c]pyridazin-8-ol (CAS 2913147-27-8), molecular formula C8H7ClF3N3O and molecular weight 253.61 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-Chloro-4-(trifluoromethyl)-5,6,7,8-tetrahydropyrido[3,2-c]pyridazin-8-ol (C8H7ClF3N3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 253.61 g/mol, it falls into the medium-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.
