Chemical Structure

1,1,1,2,3-PEntachloropropane CAS 21700-31-2 chemical structure

Description

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.

CATO supplies 1,1,1,2,3-PEntachloropropane (CAS 21700-31-2), a certified reference material (molecular formula C3H3Cl5, MW 216.32 g/mol) for analytical method development and quality control.

Owing to chlorine substitution, 1,1,1,2,3-PEntachloropropane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 216.32 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
