Chemical Structure

2-Methyl-4,5,6,7-tetrahydro-1H-benzo[d]imidazole-6-carbonyl chloride CAS 131020-47-8 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

2-Methyl-4,5,6,7-tetrahydro-1H-benzo[d]imidazole-6-carbonyl chloride (CAS 131020-47-8), molecular formula C9H11ClN2O and molecular weight 198.65 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-Methyl-4,5,6,7-tetrahydro-1H-benzo[d]imidazole-6-carbonyl chloride (C9H11ClN2O) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

As a certified reference material (CRM), 2-Methyl-4,5,6,7-tetrahydro-1H-benzo[d]imidazole-6-carbonyl 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.
