552-45-4 EQT3V044TW alpha-Chloro-o-xylene o-Xylyl chloride Benzene, 1-(chloromethyl)-2-methyl- 1-(Chloromethyl)-2-methylbenzene 2-(Chloromethyl)toluene omega-Chloro-o-xylene EINECS 209-013-8 HSDB 2681 o-Methylbenzyl chloride 2-Methylbenzyl chloride o-Xylene, alpha-chloro- o-Xylyl-alpha-chloride o-(Chloromethyl)toluene UNII-EQT3V044TW (CAS 552-45-4), molecular formula C8H15Cl and molecular weight 146.66 g/mol, is a CATO reference standard with documented purity and traceability.

552-45-4 EQT3V044TW alpha-Chloro-o-xylene o-Xylyl chloride Benzene, 1-(chloromethyl)-2-methyl- 1-(Chloromethyl)-2-methylbenzene 2-(Chloromethyl)toluene omega-Chloro-o-xylene EINECS 209-013-8 HSDB 2681 o-Methylbenzyl chloride 2-Methylbenzyl chloride o-Xylene, alpha-chloro- o-Xylyl-alpha-chloride o-(Chloromethyl)toluene UNII-EQT3V044TW (C8H15Cl) contains chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
