Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,2-Bis(bromomethyl)-3-chlorobenzene.
1,2-Bis(bromomethyl)-3-chlorobenzene (CAS 22479-40-9), molecular formula C8H7Br2Cl and molecular weight 298.40 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1,2-Bis(bromomethyl)-3-chlorobenzene (C8H7Br2Cl) contains chlorine/bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 298.40 g/mol, it falls into the medium-molecular-weight range. 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), 1,2-Bis(bromomethyl)-3-chlorobenzene 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.
