Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
8-Chloro-2-(2,5-dimethylphenyl)quinoline-4-carbonyl chloride (CAS 1160256-42-7), molecular formula C18H13Cl2NO and molecular weight 330.21 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 8-Chloro-2-(2,5-dimethylphenyl)quinoline-4-carbonyl chloride (C18H13Cl2NO) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 330.21 g/mol, it falls into the moderately-high-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.
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.
