Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Chlorobenzoyl-d4 Chloride.
4-Chlorobenzoyl-d4 Chloride (CAS 87367-51-9) is a high-purity analytical reference standard with the molecular formula C7D4Cl2O and a molecular weight of 179.04 g/mol.
Structurally, 4-Chlorobenzoyl-d4 Chloride (C7D4Cl2O) contains deuterium isotope labeling, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 179.04 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), 4-Chlorobenzoyl-d4 Chloride 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.
