5-(3-Chloropropyl)-1-Phenyl-1H-1,2,3,4-Tetrazole CAS 73963-34-5 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-(3-Chloropropyl)-1-Phenyl-1H-1,2,3,4-Tetrazole.

5-(3-Chloropropyl)-1-Phenyl-1H-1,2,3,4-Tetrazole (CAS 73963-34-5), molecular formula C10H11ClN4 and molecular weight 222.67 g/mol, is a CATO reference standard with documented purity and traceability.

5-(3-Chloropropyl)-1-Phenyl-1H-1,2,3,4-Tetrazole (C10H11ClN4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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), 5-(3-Chloropropyl)-1-Phenyl-1H-1,2,3,4-Tetrazole 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.
