Chemical Structure
Description
As a certified reference material (CRM), 2-(Chloromethyl)benzoyl cyanide 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.
2-(Chloromethyl)benzoyl cyanide (CAS 155380-13-5), molecular formula C11H11ClNO3 and molecular weight 240.66 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 2-(Chloromethyl)benzoyl cyanide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 240.66 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
