Chemical Structure
Description
CATO supplies 7-Chloro-2,3-dihydro-1H-inden-4-ol (CAS 145-94-8), a certified reference material (molecular formula C9H9ClO, MW 168.62 g/mol) for analytical method development and quality control.
7-Chloro-2,3-dihydro-1H-inden-4-ol (C9H9ClO) contains a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
