Chemical Structure
Description
2-Bromo-4-(hydroxymethyl)phenol (CAS 29922-56-3), molecular formula C7H7BrO2 and molecular weight 203.03 g/mol, is a CATO reference standard with documented purity and traceability.
2-Bromo-4-(hydroxymethyl)phenol (C7H7BrO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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-Bromo-4-(hydroxymethyl)phenol 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.
