622-98-0 1-Chloro-4-ethylbenzene EINECS 210-763-3 CAS 622-98-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 622-98-0 1-Chloro-4-ethylbenzene EINECS 210-763-3.

622-98-0 1-Chloro-4-ethylbenzene EINECS 210-763-3 (CAS 622-98-0), molecular formula C8H15Cl and molecular weight 146.66 g/mol, is a CATO reference standard with documented purity and traceability.

622-98-0 1-Chloro-4-ethylbenzene EINECS 210-763-3 (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.

As a certified reference material (CRM), 622-98-0 1-Chloro-4-ethylbenzene EINECS 210-763-3 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
