Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 228.50 g/mol gives O-(2,6-Dichlorobenzyl)hydroxylamine hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
O-(2,6-Dichlorobenzyl)hydroxylamine hydrochloride (CAS 1885-52-5) is a high-purity analytical reference standard with the molecular formula C7H7Cl2NOHCl and a molecular weight of 228.50 g/mol.
Owing to an amide group, a hydroxyl group, an ether linkage, chlorine substitution, O-(2,6-Dichlorobenzyl)hydroxylamine hydrochloride is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 228.50 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
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.
