6-Chlorochroman CAS 3722-71-2 chemical structure

Description

6-Chlorochroman (CAS 3722-71-2) is a high-purity analytical reference standard with the molecular formula C9H9ClO and a molecular weight of 168.62 g/mol.

Based on its molecular formula C9H9ClO, 6-Chlorochroman contains a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 168.62 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
