Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-chloro-2-(chloromethyl)-3-methylbenzene.
1-chloro-2-(chloromethyl)-3-methylbenzene (CAS 55676-90-9), molecular formula C8H8Cl2 and molecular weight 175.06 g/mol, is a CATO reference standard with documented purity and traceability.
1-chloro-2-(chloromethyl)-3-methylbenzene (C8H8Cl2) contains chlorine substitution, an aromatic ring system. 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1-chloro-2-(chloromethyl)-3-methylbenzene 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.
