Chemical Structure
Description
4-Hydroxybenzoic Acid-d4 (CAS 152404-47-2), molecular formula C7H2D4O3 and molecular weight 142.15 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 4-Hydroxybenzoic Acid-d4 is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 142.15 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.
CATO manufactures 4-Hydroxybenzoic Acid-d4 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.
