Chemical Structure

Chloropropylate CAS 5836-10-2 chemical structure

Description

Owing to a steroid core, a hydroxyl group, an ether linkage, chlorine substitution, Chloropropylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 339.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Chloropropylate (CAS 5836-10-2) is a high-purity analytical reference standard with the molecular formula C17H16Cl2O3 and a molecular weight of 339.21 g/mol.

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.
