Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 188.18 g/mol gives 2-Aminocyclohepta[b]pyrrole-3-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Aminocyclohepta[b]pyrrole-3-carboxylic acid (CAS 90770-92-6) is a high-purity analytical reference standard with the molecular formula C10H8N2O2 and a molecular weight of 188.18 g/mol.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 2-Aminocyclohepta[b]pyrrole-3-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 188.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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-Aminocyclohepta[b]pyrrole-3-carboxylic 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.
