As a certified reference material (CRM), 3,4,5-Trihydroxybenzoic Acid Hydrate 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.
3,4,5-Trihydroxybenzoic Acid Hydrate (CAS 5995-86-8), molecular formula C7H6O5H2O and molecular weight 188.13 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carbohydrate-derived structure, 3,4,5-Trihydroxybenzoic Acid Hydrate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 188.13 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.
