Description
CATO manufactures 1-(Cyclopent-1-en-1-yl)-1H-imidazole under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
1-(Cyclopent-1-en-1-yl)-1H-imidazole (CAS 201656-00-0), molecular formula C8H10N2 and molecular weight 134.18 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 1-(Cyclopent-1-en-1-yl)-1H-imidazole is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 134.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
