CATO supplies 2902-98-9 Acetyl chloride, chlorodiphenyl- Benzeneacetyl chloride, alpha-chloro-alpha-phenyl- (9CI) alpha-Chloro-alpha,alpha-diphenylacetyl chloride 3-09-00-03308 (Beilstein Handbook Reference) AI3-16120 BRN 0981727 Chlorodiphenylacetyl chloride alpha-Chloro-alpha-phenylbenzeneacetyl chloride Diphenylchloroacetylchloride EINECS 220-798-6 NSC 400463 (CAS 2902-98-9), a certified reference material (molecular formula C14H22Cl2O, MW 277.23 g/mol) for analytical method development and quality control.
The molecular framework of 2902-98-9 Acetyl chloride, chlorodiphenyl- Benzeneacetyl chloride, alpha-chloro-alpha-phenyl- (9CI) alpha-Chloro-alpha,alpha-diphenylacetyl chloride 3-09-00-03308 (Beilstein Handbook Reference) AI3-16120 BRN 0981727 Chlorodiphenylacetyl chloride alpha-Chloro-alpha-phenylbenzeneacetyl chloride Diphenylchloroacetylchloride EINECS 220-798-6 NSC 400463 (C14H22Cl2O) is characterized by a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
