Description

620-19-9 771291VTT8 m-Xylyl chloride Benzene, 1-(chloromethyl)-3-methyl- (9CI) alpha-Chloro-m-xylene m-Xylene, alpha-chloro- (8CI) m-(Chloromethyl)toluene 3-(Chloromethyl)toluene EINECS 210-628-9 m-Methylbenzyl chloride 3-Methylbenzyl chloride NSC 76592 m-Xylyl-alpha-chloride UNII-771291VTT8 (CAS 620-19-9), molecular formula C8H15Cl and molecular weight 146.66 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 620-19-9 771291VTT8 m-Xylyl chloride Benzene, 1-(chloromethyl)-3-methyl- (9CI) alpha-Chloro-m-xylene m-Xylene, alpha-chloro- (8CI) m-(Chloromethyl)toluene 3-(Chloromethyl)toluene EINECS 210-628-9 m-Methylbenzyl chloride 3-Methylbenzyl chloride NSC 76592 m-Xylyl-alpha-chloride UNII-771291VTT8 (C8H15Cl) is characterized by chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
