Chemical Structure

1,1,2-Trichloroethane CAS 79-00-5 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,1,2-Trichloroethane.

CATO supplies 1,1,2-Trichloroethane (CAS 79-00-5), a certified reference material (molecular formula C2H3Cl3, MW 133.40 g/mol) for analytical method development and quality control.

Owing to chlorine substitution, 1,1,2-Trichloroethane is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 133.40 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.

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.
