Chemical Structure

2,3,5-Trichlorotoluene CAS 56961-86-5 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.

2,3,5-Trichlorotoluene (CAS 56961-86-5), molecular formula C7H5Cl3 and molecular weight 195.47 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C7H5Cl3, 2,3,5-Trichlorotoluene contains chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 195.47 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.
