Chemical Structure

(4-Methylphenyl)methanesulfonyl chloride; 4-Methylbenzenemethanesulfonyl chloride; p-Methyl-|A-toluenesulfonyl chloride; p-Tolylmethanesulfonyl chloride 51419-59-1 AB1005513 CAS 51419-59-1 chemical structure

Description

CATO supplies (4-Methylphenyl)methanesulfonyl chloride; 4-Methylbenzenemethanesulfonyl chloride; p-Methyl-|A-toluenesulfonyl chloride; p-Tolylmethanesulfonyl chloride 51419-59-1 AB1005513 (CAS 51419-59-1), a certified reference material (molecular formula C8H15ClO2S, MW 210.72 g/mol) for analytical method development and quality control.

Based on its molecular formula C8H15ClO2S, (4-Methylphenyl)methanesulfonyl chloride; 4-Methylbenzenemethanesulfonyl chloride; p-Methyl-|A-toluenesulfonyl chloride; p-Tolylmethanesulfonyl chloride 51419-59-1 AB1005513 contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 210.72 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

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.
