Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(5-(3-Chlorophenyl)-2H-tetrazol-2-yl)acetic acid.
2-(5-(3-Chlorophenyl)-2H-tetrazol-2-yl)acetic acid (CAS 81595-02-0), molecular formula C9H7ClN4O2 and molecular weight 238.63 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(5-(3-Chlorophenyl)-2H-tetrazol-2-yl)acetic acid (C9H7ClN4O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 2-(5-(3-Chlorophenyl)-2H-tetrazol-2-yl)acetic acid 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.
